IB Exam Preparation Guide: A Two-Year System for the May DP Session

IB exam preparation works when it is organised around marks and mistakes, not around hours and chapters. A Diploma Programme (DP) student who spends eight weeks re-reading notes will usually feel productive and score roughly what they scored in the last mock. A student who spends the same eight weeks sorting lost marks into causes, then fixing the biggest cause first, moves. This guide shows you how to do the second thing, across all six subjects, for the International Baccalaureate (IB) May session.

It is written for DP1 and DP2 students, and for the parents who are paying for the tuition, the stationery and the stress. It covers how the exam session is built, what the two years should look like, how to use mock exams and past papers properly, how the core (Extended Essay, Theory of Knowledge and CAS) collides with revision, what each subject group tends to lose marks on, and when outside help earns its place. At the end there are links to every focused guide on this site, because no single post can carry the depth of a subject-level plan.

What does IB exam preparation actually involve?

IB exam preparation is the work of turning two years of teaching into marks on a fixed set of papers: building recall of the syllabus, practising the command terms and paper formats, rehearsing under time pressure, and finishing the coursework that sits beside the exams. It is a calendar problem as much as a knowledge problem, because six subjects, an Extended Essay, Theory of Knowledge (TOK) and Creativity, Activity, Service (CAS) all compete for the same evenings.

Three things make it different from board-exam preparation most Indian students know:

• Marks are awarded for demonstrated reasoning, against a markscheme, not for matching a model answer. Two students can write different essays and both earn full marks.
• Coursework carries real weight. Internal Assessments (IA) are typically 20% or more of a subject grade, and they are due in DP2 while mocks and revision are also in progress.
• The syllabus is assessed through unfamiliar contexts. You will rarely meet the exact question you rehearsed. You will meet a question that needs the idea you rehearsed.

If you read only one thing before planning, read the structure below. Everything else in this guide hangs from it.

The Diploma Programme is a two-year course. Higher Level (HL) subjects have 240 recommended teaching hours and Standard Level (SL) subjects 150. TOK and the Extended Essay (EE) combine for up to 3 extra points, and CAS must be completed. The exact conditions under which a diploma is awarded or withheld are the IB's, so confirm them with your school's DP coordinator. You can read the official overview at the IB Diploma Programme page.

How does the May session work for Indian students?

Almost every IB school in India enters its DP2 cohort for the May session, which suits the April-to-March academic year. Written papers run through the first weeks of May, results come out in early July, and the school's own mock examinations usually fall several months earlier, on dates each school sets for itself. November is used by a small minority of schools and by retake candidates.

That timing has three practical consequences.

First, your real deadline is earlier than May. Internal assessments, the Extended Essay and TOK work are submitted to the school well before the written papers, because teachers must mark, moderate and upload them. A student who thinks "exams are in May" and plans backwards from there will be late for three other things.

Second, mock results arrive at a useful moment, and most students waste them. A mock taken in the winter of DP2 is the best diagnostic you will ever get, because the paper is real in style and you still have months to act on it. The section on mocks below explains how to extract everything from one.

Third, the paper timetable is uneven. Some subjects have their papers bunched; others are spread over days. Your school issues the personal timetable, and the first thing a sensible student does with it is draw it on a wall calendar and count backwards to build the plan.

Past papers, markschemes and subject reports reach students through the school or the IB's official channels. Read the subject report as carefully as the paper: it is where examiners say, in plain language, what candidates did wrong last time.

Why do capable students underperform in IB exams?

Capable students underperform in IB exams mainly because they study the syllabus rather than the assessment. Knowing a topic and earning marks on it are different skills. The gap shows up in five recurring ways, and each one has a fix that costs less than extra hours.

1. 1They answer the topic, not the command term. "Evaluate" and "describe" are not the same instruction. A student who describes a policy when asked to evaluate it has written a correct paragraph that earns about half the marks.
2. 2They never time themselves. Content revision feels like progress. Timed paper practice feels like failure, so it gets postponed until March.
3. 3They revise what they enjoy. Strong topics get a third pass; weak topics get avoided. A mock reveals this brutally.
4. 4They lose coursework time to exam panic, or exam time to coursework panic. The two compete in the same months and one always loses.
5. 5They do not log errors. The same slip costs marks in October, February and May because nobody wrote it down in October.

Notice that none of these is about intelligence or even effort. They are system failures, which is why a system fixes them. For a full treatment of one subject where this is acute, see the flagship guide on how to score a 7 in IB Math AA HL; the same diagnosis applies, with different content, to every subject here.

What does a two-year revision calendar look like for the Diploma?

A workable calendar has four phases: build in DP1, consolidate at the end of DP1, rehearse in the first half of DP2, and compress in the final term. The aim of each phase is different, and mixing them up is the commonest planning error. Students who "start revising" in DP1 with exam-paper marathons burn out; students who only build until February of DP2 never rehearse.

DP1: build, and keep a record

In DP1 the job is to understand material well enough that you could teach it. Do not treat this as pre-revision. Keep three things running from week one: a one-page summary per unit written from memory, a list of questions you got wrong and why, and a record of every command term your teachers use in feedback. By the end of DP1 you should have a first pass over roughly half of each course and, more importantly, no weak topic that you have been quietly avoiding.

DP1 is also when the long-lead items start. The EE research question, the IA topics in each subject and a CAS rhythm all need attention while exams feel distant. How these three interact is mapped in the IB DP core timeline, and every term there is built to protect your revision time later.

Summer between DP1 and DP2

This is the most undervalued window of the whole programme. Aim for modest, regular work, not a heroic push: finish reading set texts, complete one IA draft section per subject if your teachers allow it, and do a light pass over the DP1 error log. Students who disappear into the summer return in July with half their DP1 knowledge gone; students who keep a 45-minute daily habit return with a head start that compounds.

DP2 first half: coursework and first papers

The pressure peaks here. IA deadlines, EE submission, TOK work and university applications all arrive together. Protect one thing: a weekly timed block of paper practice in each core subject, even if it is only 40 minutes of a single section. It keeps exam muscles warm. Treat any week without it as a debt to be repaid the following week.

DP2 winter: mocks as a diagnostic

Mocks are the pivot of the whole plan. What you do in the three weeks after them matters more than what you did in the three weeks before. More on this in the next section.

DP2 final term: compress, rotate, rest

By now new learning should be rare. The work is retrieval, paper practice, and keeping your sleep and nutrition steady enough to perform. The last month has its own structure, covered day by day in what toppers do in the last 30 days before IB exams. Read it at the start of the final term, not in the last week.

How should you use IB mock exams?

Use an IB mock as a diagnostic, not a verdict. The score tells you where you stand; the lost marks tell you what to do. A mock is only useful if, within a week of getting it back, you have turned every dropped mark into a cause and every cause into a scheduled fix.

Here is a short process that works for any subject:

1. 1Mark your own script against the markscheme, even if the teacher has marked it. You will see how marks are really awarded.
2. 2List every lost mark with the question number, the marks lost and a one-line reason.
3. 3Tag each loss as one of four causes: knowledge gap, method error, command-term or presentation error, or time pressure.
4. 4Count the tags. The biggest bucket is your priority. If time pressure dominates, do not revise content; do timed sections.
5. 5Schedule fixes into the next three weeks: a topic to relearn, a technique to drill, or a paper section to repeat.
6. 6Retest the same weak areas with fresh questions two weeks later. If the mark does not move, the diagnosis was wrong.

The proportions will not match yours, and that is the point. A student whose log is dominated by presentation losses should not buy more content notes. A student whose log is mostly knowledge gaps should not be doing more past papers until the gaps close.

Mock-day behaviour that changes outcomes

Take the mock as if it counted. Eat as you would in May, wear what you would wear, and do not look at your phone between papers. Practise the logistics: how you write your candidate details, how you check the paper for printing errors, how you read the whole paper in the first five minutes and mark the questions you will attack first. These are small habits, and they are the reason some students lose no marks to panic in the real thing.

If the mock goes badly

A poor mock is the cheapest possible failure. It is February, not May. Resist two reflexes: "I need to study all night" and "mocks are not like the real exam". The first produces collapse; the second throws away the one dataset that matters. Sit down with the lost-mark list, find the top two causes and build the next three weeks around them. A student who treats a bad mock with that calm is already a different candidate.

How do you use IB past papers without wasting them?

Past papers are finite, so spend them in the right order. Early in DP2, use them by topic to learn what the questions look like. In the spring, use them as full timed papers. In the last month, use them as rehearsal for the exact paper rhythm. Never burn all your recent papers early because you want the "feel"; keep the most recent two or three for the final fortnight.

A good past-paper session has five parts: attempt cold under time, mark honestly with the markscheme, rewrite two answers that lost marks in full, log the errors, and re-attempt one weak question after a gap of a few days. The rewriting is the step students skip, and it is the step that teaches. Marking without rewriting is like watching someone else lift weights.

Read the examiner's report

Subject reports describe how candidates answered each question, where the common mistakes were and what the best scripts did. They are the closest thing to a free tutor's diagnostic. Read the report for the session whose paper you just attempted, and write three bullet points of what you will do differently.

Command terms are marks

Define, describe, explain, evaluate, discuss and "to what extent" set how deep an answer must go. A command term maps to a type of mark, and misreading it is the most common unforced loss across the humanities and sciences. A full treatment, with worked examples and how each term maps to mark allocation, sits in IB command terms explained with real examples. Print its table and tape it where you study.

How do IAs, the Extended Essay, TOK and CAS collide with revision?

They collide in the same four months. In DP2, subject IAs, the Extended Essay (EE), the TOK essay and exhibition, and CAS reflections all have deadlines between August and the winter break, and every hour spent firefighting one is an hour not spent on mock preparation. The solution is to finish early, not to work late.

Rules of thumb that save weeks:

• Cap each IA's remaining time. Decide in advance how many hours the final polish gets, and stop there. Perfectionism on a 20% component can cost marks on an 80% one.
• Finish the EE before the mocks. The Extended Essay is up to 4,000 words and roughly 40 hours of work. A draft that is still alive in January will eat your mock preparation. The research and writing process is covered in how to write an IB Extended Essay.
• Treat TOK as two deadlines. The exhibition is internally assessed and the essay is externally assessed; both need drafts earlier than students expect.
• Log CAS in small, steady pieces. CAS must be completed; leaving the reflections to the last week is a recurring scramble.

Internal assessment is also where the line between help and misconduct is sharpest. Every IA must be the student's own work. A teacher may give feedback on one draft; nobody, tutor or parent, may write or edit the submission. The full rules, the criteria logic and the limits of teacher feedback are in the IB Internal Assessment guide, and examples of what strong and weak work look like by subject are collected in IB IA examples.

Where does each subject group lose marks?

Each subject group loses marks in a characteristic way, so revision should look different for each. A student carrying a language, a science, a humanities subject and maths needs four modes of preparation, not one study method applied six times.

Mathematics

DP Mathematics comes in two subjects, Analysis and Approaches (AA) and Applications and Interpretation (AI), each at HL and SL. The two papers that follow a no-calculator-then-calculator pattern reward different habits: hand fluency on one, interpretation and efficient technology use on the other. Students who rehearse only one mode lose marks on the other. If you are weighing how to finish the maths revision, the detailed AA HL plan in how to prepare for IB DP Mathematics AA HL and the paper-by-paper work in IB Math AA HL paper preparation go much deeper than a hub can.

Sciences

The DP sciences, first assessed in 2025, have a Paper 1 in two parts (1A multiple choice and 1B data-based questions) and a Paper 2 of short-answer and extended-response questions. The internal assessment is a scientific investigation worth 20%, marked on four criteria of 6 marks each. The recurring losses are in the data-based section (misreading axes, dropping units) and in extended answers that list facts without linking them. For subject-specific advice, see IB Physics HL most important topics and study plan and why students struggle in IB Chemistry and how to fix it.

Economics and humanities

Economics has an extended-response paper, a data-response paper and, at HL, a policy paper. Its internal assessment is a portfolio of three commentaries on published news articles. The recurring mistake is describing a mechanism correctly and never reaching the evaluation the command term asks for. The cure is to practise writing the evaluation sentence first, then adding the explanation that supports it.

English and languages

English A papers are tested through unseen-passage analysis, comparative essays and an oral. The pattern that loses marks is a long, unstructured start. Students who plan for five minutes before writing outscore students who start immediately, even when the second group knows more. Language B (for students whose first language is not English) is built around five themes and separates receptive from productive skills, so listening and reading practice and writing practice need separate slots.

What should a weekly revision timetable look like?

A good weekly timetable has a fixed shape, so decisions about what to study stop eating energy. It reserves protected slots for the activities that move marks, leaves unscheduled time for the unexpected, and includes rest as a line item. A common failure is a timetable so full that one missed evening collapses the week.

Below is an example for a DP2 student in the spring term. It is a template to adjust, not a prescription.

Three principles keep it honest:

• Rotate subjects; do not block them. Three hours of one subject produces diminishing returns after the first hour. Short, varied blocks lead to better retrieval.
• Put the hardest subject in your best hour, not the last one of the evening.
• Review before you move on. Every session opens with five minutes on the previous session's weak point.

For families that follow a coaching schedule, a school day and a tutor, the plan has to be built around fixed commitments first. Start with the weekly structure, then slot tutoring where the weakest bucket is.

How do you revise so that it sticks?

Revision sticks when it forces you to retrieve information rather than recognise it. Re-reading notes feels fluent because the material is on the page; retrieving it from memory feels hard because it is. The hardness is the learning. The techniques below all use that principle.

• Blank-page recall. After studying a topic, close everything and write down all you remember in five minutes. Then check what you missed. Do this at intervals of one day, one week and one month.
• Question-first revision. Start from a past-paper question and work backwards to the notes you need. You revise what the exam asks, not what the textbook offers.
• Teach it aloud. Explain a concept to a family member or a wall. Every stumble is a gap.
• Interleaving. Mix topics inside a session. Blocked practice flatters you; mixed practice looks like the exam.
• Error-log flashcards. Turn your recurring mistakes into one-line cards: "Dropped units in 1B questions", "Used describe-level answer for an evaluate". Read them before every paper.

What not to do

Highlighting an entire page, copying notes in a prettier format, watching a lecture at double speed and calling it revision all feel like work and produce little. If a technique leaves you comfortable, check whether it asked you to recall anything.

How do you manage exam stress and stay healthy?

Manage exam stress by making the plan smaller, the routine steadier and the body better-supported. Anxiety usually spikes when the work feels undefined. A written plan for the week, with an end-of-day stop time, removes more anxiety than any breathing exercise, though breathing exercises help too.

Practical anchors that work for students at this stage:

• Protect sleep. A student who sleeps six hours and studies two extra loses more than they gain, especially in subjects that need quantitative reasoning.
• Stop at a fixed hour. Work expands to fill the night if you let it. A hard stop makes the next day better.
• Move daily. A walk or a short game is enough. It is not time off from IB exam preparation; it is part of it.
• Eat on a schedule, especially on mock days, so the real exam is not the first time you test your routine.
• Talk early. If a student has been low or unable to sleep for more than a couple of weeks, the school counsellor and the family doctor are the right people, before the exam period rather than during it.

Parents often ask how involved to be. The honest answer is: ask about the plan, not the marks. "What is the focus this week and what do you need from me?" produces calm. "What did you get?" produces defensiveness. If you are a parent, your most useful contribution is a quiet home, regular meals and a steady tone.

When does a tutor help, and when does it not?

A tutor helps when the student has a specific, diagnosable gap that a school class cannot close: a topic that never clicked, a repeated pattern of lost marks, or a subject where the school teacher is stretched. A tutor does not help when the real issue is time, sleep or avoidance, because adding another session to an overloaded week makes it worse.

Check these before booking anything:

1. 1Do you have a lost-mark list from a recent paper or mock? Without it you cannot tell a tutor what to fix.
2. 2Is the issue knowledge, technique or time? Tutoring is strongest on knowledge and technique, weaker on time.
3. 3Is there room in the week? A tutor session that replaces a lower-value block is a gain. One that sits on top of a full schedule is a cost.
4. 4Will the tutor teach the skill or do the work? For anything coursework-based, a tutor may teach and question but must not write or edit the submission.

Many families, particularly in Gurgaon and the NCR, also ask whether home or online tutoring suits exam season. Home sessions give focus and space without travel; online sessions remove travel from busy weeks and allow a specialist from anywhere. The trade-offs are covered in IB home tutor vs online tutor in Gurgaon, and the question of timing in when to start IB tutoring.

IB Gram is an independent tutor-matching platform. A family sends a query or books a free consultation, and IB Gram asks about the programme, level, subject, school calendar, location and schedule. It then shortlists tutors whose profiles are verified and fit. A demo or trial session can be arranged before the family commits, and the family can ask for a different match. Lessons run at home, online or hybrid, subject to tutor availability. No tutor can guarantee a grade, and you should be wary of anyone who does. Tutors for the Diploma in Gurgaon are listed on the IB DP tutors in Gurgaon page, with subject pages such as IB Physics tutors in Gurugram and IB Chemistry tutors in Gurugram.

What about retakes and a second chance?

A DP candidate who wants a higher grade or who missed the diploma can register for a later session through a school, normally the one they sat with, most often the following November. Internal assessment marks are usually carried forward, so a retake mostly targets the externally assessed papers. That makes retake preparation more focused than a first attempt: you already know your IA marks, so you know exactly how much the papers must carry.

Before deciding, ask the DP coordinator three questions: whether you are eligible, what the deadlines are, and whether an enquiry upon results (a re-mark) is worth requesting first, since that has a short window after results are released. Eligibility, deadlines and costs are the IB's and the school's to confirm; do not rely on hearsay from other families.

A retake plan is built the same way as the main one: diagnose the lost marks in the papers you sat, then rebuild only those areas. Starting with the old notes is the mistake. Start with the old scripts.

What does a good revision session look like in practice?

A good session has a clear target, a start ritual, an active core and a short close. Consider a DP2 student revising Economics on a Tuesday evening. She opens with the target: "Write two evaluation paragraphs on exchange-rate policy under time." She spends 10 minutes recalling the mechanisms from a blank page, 25 minutes writing the paragraphs, 10 minutes marking them against the markscheme criteria, and 10 minutes rewriting the weaker one. She ends by writing one line in the error log: "Evaluation sentence came last, so no marks for judgement; start with it." That 55-minute block does more than two hours of rereading.

Compare it with the same student reading the same chapter for two hours. She feels exhausted and recalls perhaps a third of it by the weekend. The session with the target and the marking is shorter and produces something she can retest.

The same shape works elsewhere. A maths student sets a target, such as "three Paper 1 questions on integration in 20 minutes", does them under time, marks them and logs one error. A Biology student writes a six-mark answer on enzyme action from memory, checks it against the markscheme and rewrites it. The content differs; the structure is constant.

What are the most common IB exam preparation mistakes?

The mistakes below recur across schools and years. Most are cheap to fix once seen.

If you recognise three or more of these, do not try to fix them all at once. Pick the one that costs the most marks, fix it for two weeks, then move on.

Frequently Asked Questions

When should I start IB exam preparation?

Start building the habits in the first term of DP1, and start formal revision by the autumn of DP2. In DP1, the job is to understand the material and keep an error log; in DP2 the job shifts to retrieval and timed papers. Starting intense revision in DP1 usually burns students out, while starting in March of DP2 leaves too little time to act on mock feedback. Aim for steady work, not heroic bursts.

How many hours a day should an IB student study?

There is no single number, because it depends on the term, the subject load and the student. A realistic pattern is a couple of focused hours on weekday evenings and longer weekend blocks, adjusted around IA and EE deadlines. Quality matters more than volume: a student who sleeps well and does two hours of marked past-paper work usually beats one who reads notes for five.

Are past papers enough for IB revision?

Past papers are necessary but not enough on their own. They show format and difficulty, but they only help if you mark them against the markscheme, rewrite weak answers and log errors. Content gaps need teaching or recall practice first. A student who does papers without fixing the topics behind the lost marks repeats the same scores. Pair every paper with a short list of fixes.

What if my mock results are very low?

A low mock is useful information, not a prediction. Mark the script yourself, list every lost mark, tag each as knowledge, method, command term or time, and fix the biggest bucket first. Speak to your teacher and, if useful, a tutor with that list in hand. Most improvement between a February mock and the May exam comes from fixing a few repeated, avoidable errors.

How do I balance the Extended Essay, TOK and CAS with revision?

Finish the core early and cap the time on each piece. Set submission targets before the winter mocks, treat TOK as two deadlines (exhibition and essay), and log CAS in small steady pieces. The aim is to enter the mock period with the core essentially done, so spring is only for papers. The timeline for this is in the IB DP core planning guide.

Does an IB tutor help with exam preparation?

A tutor helps when the student has a specific diagnosable gap, such as a topic that never clicked or a repeated mistake pattern. It helps less when the problem is an overloaded week or poor sleep. For coursework, a tutor may teach skills and ask questions but must not write or edit the student's work. No tutor can guarantee a grade, so judge a tutor by how clearly they diagnose and plan.

Can I do IB exam preparation online?

Yes, online sessions work well for exam preparation, especially for timed paper review, markscheme analysis and doubt-solving, and they remove travel from busy weeks. They suit self-directed students with a quiet space and a stable connection. Some students concentrate better at home with a tutor in the room. A hybrid, with most sessions online and occasional in-person work, is common. Ask for a trial session before committing.

What is the difference between IB revision and board-exam revision?

IB revision is organised around command terms, markschemes and unfamiliar contexts, whereas board-exam revision often rewards memorised answers. In the IB, two different answers can both earn full marks if they show the required reasoning. That means you practise reasoning in new contexts, not rote recall of model answers. Coursework also carries weight, so planning has to include IA and the Extended Essay.

Is it too late to improve if I start revising in March?

It is not too late, but the gains will be narrower and need a tighter plan. In March, triage: use your last mock to find the two or three topics per subject that cost the most marks, work on those, and rehearse timed papers. You will not rebuild a whole syllabus, but you can recover the avoidable marks that separate a grade from the next one.

How do I reduce exam anxiety before the May session?

Make the work smaller and the routine steadier. Write a weekly plan with a firm stop time, protect sleep, move daily and rehearse exam logistics through mocks. Talk to the school counsellor or a doctor if low mood or sleeplessness lasts more than a couple of weeks. Parents help most by asking about the plan, not the marks, and keeping the home calm.

Next steps

1. 1Draw your personal paper timetable on a wall calendar, and mark the IA, EE and TOK deadlines on the same sheet.
2. 2Take your last paper or mock and build a lost-mark list tagged by cause; pick the biggest bucket.
3. 3Book the three-week fix plan into your timetable, and retest the same weak areas with fresh questions after two weeks.
