Most IB students study hard. The ones who score 7s study differently.
After marking thousands of exam papers across multiple May and November sessions, our IB examiner team at IB Demystified knows exactly what separates a grade 5 student from a grade 7 student. It is rarely raw intelligence. It is almost always preparation strategy — knowing what to study, how to practise it, and when to switch from learning mode to exam mode.
This guide gives you everything: a realistic week-by-week revision timeline, the right way to use past papers, how to decode IB command terms, subject-specific tips from the people who write and mark the papers, and the common mistakes we see costing students marks every single session. No filler. No generic advice. Just what actually works.
Here is something that surprises most students when we tell them: re-reading notes is one of the least effective ways to revise. It feels productive. You recognise the content. Your brain tells you that you know it. But recognition and recall are completely different skills — and the IB exam tests recall, under pressure, on paper.
We see the same pattern every session. A student spends six weeks re-reading notes and highlighting textbooks. They feel prepared. Then they sit in the exam and struggle to structure an Evaluate question or remember the exact mark scheme answer for a Calculate task. That gap between feeling ready and being ready is where most marks disappear.
If you are also wondering whether the IB is the right programme for you compared to A Levels, it is worth understanding upfront that the IB’s breadth is both the challenge and the opportunity — six subjects means six separate revision plans running simultaneously.
The biggest mistake IB students make: Spending 80% of revision time reading and only 20% practising. Top-scoring students flip this ratio — they spend most of their time doing past papers, writing practice answers, and testing themselves actively.
The good news is that once you understand this, fixing it is straightforward. The rest of this guide shows you exactly how.
Before you revise a single topic, you need to understand how your IB score is calculated. This is one of those things that seems obvious but that most students have never actually sat down and worked through properly.
Your final IB grade in each subject is a number between 1 and 7. It comes from two components:
Your total IB Diploma score runs from 1 to 45. You get up to 42 points from six subjects (7 points each) and up to 3 bonus points from Theory of Knowledge and the Extended Essay combined. To earn the diploma, you need a minimum of 24 points — but most competitive university offers require 32 to 38 or above.
| IB grade | Meaning | Typical % threshold |
|---|---|---|
| 7 | Excellent | 75 – 85% (varies by subject and session) |
| 6 | Very Good | 65 – 74% |
| 5 | Good | 55 – 64% |
| 4 | Satisfactory | 45 – 54% |
| 3 | Mediocre | 35 – 44% |
One thing that surprises students: grade boundaries shift every session. The IB adjusts them based on overall student performance globally. A paper that was harder than usual will have lower grade boundaries. This means chasing a specific percentage is less useful than building genuine understanding of every topic in your syllabus.
Practical takeaway: Students who aim for deep understanding consistently outperform students who aim for a specific mark target. Boundaries move. Understanding does not.
The May 2026 IB exam session runs from 24 April to 20 May 2026. Here is a structured timeline working backwards from exam day. Most students make the mistake of treating January and February as the real start of revision — by then, you only have 10 to 14 weeks, which sounds like a lot until you account for mock exams, IA deadlines, TOK, and six subjects running at once.
If you are doing the DP2 revision courses, these are designed to slot directly into this timeline — they run in the weeks leading up to exams and assume you already have your content foundations in place.
Go through the official IB syllabus for every subject. List every topic. Mark each one honestly: strong, shaky, or weak. This audit tells you exactly where your time should go. Do not revise topics you already know well — that is comfortable but not useful.
Work through your weak and shaky topics systematically. Use active recall — close your notes and write everything you remember before checking. Do 2 to 3 topic-based past paper questions per week per subject. Start your error log now (more on this below).
Switch from topic revision to full past papers under timed conditions. One complete paper per subject per week minimum. After each paper, mark it against the mark scheme and identify every lost mark. This is the highest-value activity in your entire revision period.
Simulate exact exam conditions: desk, timer, no notes, no phone. After each paper, review your error log and re-test the topics you keep losing marks on. Do not start learning new content at this stage — the anxiety it creates is not worth the marginal mark gain.
Review key formulas, definitions, and command terms. Skim your error log. Do one or two individual questions, not full papers. Sleep at least 8 hours every night this week — the research on sleep and memory consolidation is unambiguous. Sleep is revision.
Past papers are the most powerful revision tool available to IB students. But most students use them wrong. They do a paper, check their score, feel good or bad, and move on. That is not revision. That is testing. The difference matters enormously.
This approach applies across all subjects — whether you are working on IB Math AA HL, IB Physics Paper 2, or any other subject in the programme.
Put your phone away. Close your notes. Set a timer. Do not stop when time is up — this is non-negotiable. The pressure of the clock is part of what you are training for. Students who consistently practise under timed conditions perform significantly better on exam day than those who work at their own pace.
Go through the mark scheme line by line. Award marks for what you got right. But crucially — read every mark scheme answer for every question, including the ones you got correct. The mark scheme shows you exactly what the IB expects. Many students write the right answer in the wrong way and lose marks they should have kept.
For every mark you lost, write it down: the topic, the command term, and why you lost it. Was it a content gap? Did you misread the question? Did you run out of time? Did you know the answer but phrase it incorrectly? After a few papers, patterns emerge — and those patterns are your personal priority list for the remaining revision weeks.
Go back to every question you got wrong and redo it from scratch — without looking at the mark scheme. This is spaced repetition in practice. If you still cannot answer it correctly, it needs more work. If you nail it, you have genuinely learned it. This single habit is responsible for more grade improvements than any other technique we recommend.
The IB updated many syllabuses around 2019 and 2020. Papers before 2018 may include topics or question formats that are no longer examined. Focus on recent papers — they are more representative of what you will face and are usually harder, which makes them better practice.
Target: A minimum of 10 to 15 complete past papers per subject in the final 8 weeks of revision. For HL subjects, aim for the higher end. Students who consistently hit this target almost never underperform on exam day.
IB examiners mark to the command term. This is not a suggestion — it is the basis of how your answers are evaluated. A student who writes four detailed paragraphs in response to a “State” question will score 1 mark. The student who writes one precise sentence will also score 1 mark. Same result, for a fraction of the time spent.
Understanding command terms takes less than two hours to do properly and is one of the highest-return activities in your entire revision period. This applies equally whether you are sitting IB Diploma subjects, A Levels, or IGCSE.
| Command term | What it actually means | Common mistake |
|---|---|---|
| State | Give a brief, specific answer — one word or a short phrase | Writing full explanations when a one-word answer was needed |
| Define | Give the precise formal meaning of a term | Using vague everyday language instead of technical definition |
| Outline | Give a brief account or summary — more than State, less than Explain | Either too brief or too long — students misjudge the depth required |
| Explain | Give reasons or causes — the “why” and “how”, not just the “what” | Describing what happens without explaining the mechanism behind it |
| Calculate | Show all working steps leading to a numerical answer | Writing only the final answer — method marks exist independently |
| Analyse | Break into component parts and examine their relationships | Just describing instead of breaking down and examining links |
| Evaluate | Make a judgment based on evidence — strengths, limitations, conclusion | Listing pros and cons without making a clear overall judgment |
| Discuss | Give different perspectives or arguments and link them together | Writing only one side, or two sides without linking them |
| Compare | Describe similarities and differences | Only describing one option without mentioning the other |
| Justify | Give valid reasons or evidence to support a conclusion | Stating a conclusion without the reasons or evidence behind it |
Print this table. Stick it somewhere visible. Before writing any practice answer, check the command term first. Ask yourself: is my response actually doing what this command term requires? Students who build this habit consistently pick up 3 to 5 extra marks per paper — marks that were always available to them but were being left on the table.
General strategies only get you so far. Each IB subject has its own quirks — specific question types, specific marking patterns, and specific ways students keep losing marks unnecessarily. Here are the most important ones.
Show every single step of your working. In IB Math, method marks exist independently of the final answer. If you make a calculation error mid-way through but continue with correct logic, you can still earn all subsequent marks. Students who skip steps lose those method marks even when their final answer is correct — a painful and entirely avoidable loss.
For Paper 1 (no calculator), practise mental arithmetic and algebraic manipulation until they are second nature. For Paper 2 and Paper 3, know your GDC inside out. Many students know the mathematics but lose time fumbling through calculator menus under exam pressure. Practise using your GDC as part of your revision, not as a side activity.
If you are struggling with any specific area of the syllabus, our 1:1 IB tutoring sessions are available for both DP1 and DP2 students at every level.
Data-based questions (DBQs) are where most marks are unnecessarily lost. These give you a graph, table, or dataset you have never seen before and ask you to interpret it. The content knowledge required is minimal — the skill being tested is scientific reasoning. Practise these questions separately from content revision, because they require a different kind of thinking.
In written responses, use precise scientific vocabulary at all times. Replace “goes up” with “increases”, “goes down” with “decreases”, “lots of” with “significantly greater” or give a specific numerical value. Examiners look for this precision — it is worth marks on every paper.
For specific subject support, take a look at our IB examiner tutors — many are active examiners in Biology, Chemistry, and Physics who can tell you exactly what their mark schemes look for.
Use diagrams wherever the question allows it, and label them completely. A well-drawn, fully-labelled supply and demand diagram with a clear shift and correctly labelled P and Q axes can earn 3 to 4 marks on its own. Many students draw diagrams but leave axes unlabelled or forget to show the shift — that is free marks being left on the table.
For evaluation questions — typically the final section of a multi-part question — structure your answer as: argument for, argument against, and a clear judgment that depends on a specific condition. “It depends on whether…” followed by a genuine explanation of that condition is exactly what top mark band answers look like in every examiner report we have seen.
Paper 1 is a reading task first and a writing task second. Students who rush through annotation and go straight to writing almost always produce weaker analysis. Spend the first 10 to 12 minutes annotating the text and planning your response structure. The writing itself goes faster when you have a clear plan, and the quality is significantly higher. Our guide on the difference between IB English Literature and Language is worth reading if you are deciding between options.
Avoid describing what a text says (content) instead of how it says it (technique and effect). Every analytical point should follow this structure: identify the technique, quote it, and explain what effect it has on the reader and why the writer chose it. That pattern is what separates a grade 5 Paper 1 from a grade 7 one.
Know your essay structures before exam day. Essay questions in Group 3 subjects reward well-organised, evidence-supported arguments — not streams of knowledge. Practise writing timed essay plans (not full essays) for past paper questions. You should be able to produce a structured outline for any essay question in under 8 minutes. The plan forces you to think before you write, which dramatically improves the quality of the answer that follows.
These come directly from examiner reports and from what we see when students come to us after disappointing results. Every single one is avoidable — but only if you know to look for them.
Close your notes. Write down everything you can remember about a topic. Then check what you missed. This is active recall, and the research consistently shows it produces far better long-term retention than re-reading or highlighting. It is also harder and more uncomfortable — which is precisely why it works. Discomfort during revision is usually a sign you are doing it right.
Do not revise a topic once and consider it done. Return to it after 3 days, then a week, then two weeks. Each time you retrieve information from memory, the memory becomes stronger and more durable. This is the basis of spaced repetition — the same principle behind Anki and other flashcard systems. You can apply it without any app by simply scheduling topic reviews on a calendar. Our guide on study tips and motivation covers this in more detail alongside practical strategies for staying consistent.
If there is a topic you genuinely do not understand, try explaining it out loud as if you were teaching it to a 12-year-old. Any point where your explanation becomes vague or breaks down is exactly where your understanding has a gap. This technique is uncomfortable precisely because it exposes what you do not know — which is what revision is supposed to do.
Work in 45 to 50-minute focused blocks with 10 to 15-minute breaks between them. During the break, step away from your desk entirely. Walk around. Get some water. Do not scroll through your phone — that is not rest for your brain. Students who study in focused blocks with real breaks consistently outperform students who spend 8 hours at a desk while gradually losing concentration from hour three onwards.
This gets dismissed by students who feel they cannot spare the time. The evidence says the opposite: 30 minutes of moderate exercise improves memory consolidation, reduces cortisol, and sharpens focus for the study session that follows. Even a 20-minute walk counts. Students who exercise regularly during exam preparation consistently report lower anxiety and perform closer to their true ability on exam day.
The week before exams is not the time for intensive new revision. It is the time for consolidation, confidence, and preparation. Here is what our examiner team actually recommends for this period:
What not to do: Do not start learning new content the week before your exam. If something is not in your revision notes by this point, trying to learn it in three days creates anxiety without meaningful mark gain. Focus on what you already know and ensure you can access it reliably under pressure.
If you did not get the results you were hoping for after the exam session, our guide on IB exam retakes covers the full policy, costs, and November retake options — including how to approach retake preparation differently from first-sitting preparation. We also have specialist support available through our IB Retakes programme for students who need to resit.
Some IB subjects are genuinely very difficult, especially at Higher Level. Many students struggle with subjects like IB Mathematics, Physics HL, Chemistry HL, and Economics HL — not because they lack ability, but because the gap between understanding content and answering IB exam questions in the way examiners reward is wider than most students expect.
Working with an experienced IB tutor makes a measurable difference when:
The key difference at IB Demystified is that our tutors are not just IB-familiar teachers — many are active IB examiners who mark papers in the very sessions your students will be sitting. That means they know exactly what is on the current mark scheme, which topics were examined most recently, and what distinction between a 5 and a 7 answer actually looks like on paper. You can view our full range of 1:1 tutoring packages to find the right level of support for your situation.
We also offer support beyond the IB Diploma — including A Level tutoring, IGCSE tutoring, GCSE tutoring, and AP tutoring for students across different curricula.
Most IB students who achieve 6s and 7s study 2 to 3 hours per subject per week throughout the two-year programme, then increase to 4 to 5 hours per subject in the final 8 weeks. Completing 10 to 15 past papers per subject in the final term is the standard for top performers. Quality and consistency matter more than total hours — unfocused study for 8 hours is less valuable than 2 hours of active recall and past paper work.
Aim for at least 10 to 15 complete past papers per subject under timed conditions. Focus on papers from 2018 onwards as they reflect the current syllabus. Space them out across your revision period so you have material to practise with right up to exam week — do not burn through all your papers in one go in week one.
IB command terms are the specific instruction words used in exam questions — Analyse, Evaluate, Explain, Calculate, Outline, Discuss, and so on. Each has a precise definition set by the IB. Examiners mark to the command term, meaning a student who misinterprets “Evaluate” and only describes can lose 3 to 4 marks per question even when their content knowledge is strong. Learning all the command terms thoroughly is one of the highest-return revision activities available.
Start structured revision no later than 12 weeks before your first exam. Most top-performing IB students begin light revision in January for May exams. Waiting until after mock exams in February or March only leaves 6 to 8 weeks — which is genuinely not enough time for HL subjects with large syllabuses. Starting earlier gives you time to identify weak areas and address them before the exam pressure sets in.
The IB Diploma is generally considered broader than A Levels — you study six subjects simultaneously rather than specialising in three or four. HL IB subjects are comparable in depth to A Levels. The additional core components — Theory of Knowledge, Extended Essay, and CAS — make the IB significantly more demanding in terms of workload management, even where individual subject content is similar. We have a full comparison guide on IB vs A Levels if you are deciding between the two.
In our experience, the biggest impact comes from a tutor who knows the marking criteria — not just the subject content. An IB examiner reading your practice answers and telling you exactly why you lost marks is qualitatively different from a subject expert who has never seen a real mark scheme. That is why examiner-led tutoring consistently moves students from grade 4–5 to grade 6–7 within a few focused sessions. You can view our tutoring packages to find the right option for your needs.
