About 190,000 students sit the IB Diploma each May, and the global mean score sits stubbornly around 30 out of 45. If you are figuring out how to study for IB exams, the generic advice to "use past papers and revise early" hides the fact that IB is six subjects, three core requirements, and two assessment systems running in parallel for two years. Treating it like a single exam is how 7s become 5s.
This is a 12-month plan written for the May 2026 cohort and anyone starting DP2. You will get a month-by-month timeline that respects Internal Assessment{target="_blank" rel="noopener noreferrer"} deadlines, an honest split between HL and SL prep, evidence-based techniques from cognitive science, and a workflow for past papers that does not melt your brain.
Notesmakr is an AI-powered notes maker that turns IB subject guides, textbook PDFs, and your own handwritten notes into smart flashcards, quizzes, and mind maps. So the strategies below are not just theory. They plug into tools that handle the boring parts (carding, scheduling, quizzing) so you can spend more time on the thinking parts.
Why IB Demands a Different Study Plan
Every "how to study for IB exams" article tells you to make a schedule, do past papers, and sleep. True. Useless on its own.
The real problem with IB is that it is six subjects plus three core components (Extended Essay, TOK, CAS) running on overlapping deadlines for 24 months. Your IA in Biology is due the same month you are drafting your EE and revising for mocks. If you treat each piece separately, you will hit DP2 February with three IAs unfinished and zero time for past papers. That is the IB failure mode.
The second problem is that HL is not just "more SL." HL subjects have extra paper components, deeper content, and harder mark schemes. According to the IBO subject guides, HL subjects expect roughly 240 teaching hours versus 150 for SL. Your revision split needs to reflect that, not your timetable.
The IB is two assessment streams running at once. Internal assessments (IAs, EE, TOK) lock in 20-30% of each subject grade before exams start. Externals (Paper 1/2/3) decide the rest in May. A 12-month plan that ignores either stream leaves points on the table.
The third problem: most IB students study HL and SL the same way, with the same hours per subject. Wrong. HL Maths, Biology, History, and Physics each take roughly 50-60% more revision time than their SL versions. Tilt your hours accordingly.
The 12-Month IB Study Plan (DP2 Year)
Here is a realistic timeline starting May of your DP1 year, leading to the May 2026 exam sitting. Adjust month names by 12 if you are sitting November 2026.
DP1 exams are wrapping up. Use the post-exam window to lock in your IA topics across all six subjects. Talk to subject teachers. A weak IA topic chosen in DP2 February is the single biggest predictor of a low final grade. Choose now, while you still have brain space.
Start a Notesmakr collection per subject. Import any class notes or textbook PDFs you already have. The point is not to revise yet. It is to set up the system you will use for the next 11 months.
Spend 30-40 hours on your Extended Essay during summer break. The IBO allocates 40 hours of student work to the EE. Doing 30 of them now means you spend DP2 polishing, not drafting from scratch in November while juggling IAs.
Read ahead in your two hardest HL subjects. For HL History, that means reading the prescribed topic textbooks. For HL Maths, work through the next-term content slowly so class lectures become revision, not first exposure.
DP2 begins. Class is now both new content AND IA work. Get data collection finished by mid-October for science IAs (Biology, Chemistry, Physics, Environmental Systems). For Maths IAs, finalise your research question and methodology. For language IAs, start your individual oral practice.
Build a flashcard deck for each subject as content gets taught. Do not wait until "revision time." Cloze deletion cards work well for definitions, dates, formulas. The fill-in-the-blank format forces recall rather than recognition.
EE is typically due to your school in late November or early December. Submit a polished version, not a "good enough" one. Examiners reward clarity of research question and historical/scientific reasoning over volume. Top-scoring EEs use 10-20 quality sources, not 40 mediocre ones.
IAs in most subjects are due by mid-January. Get first drafts to teachers in December for feedback. This is also when you should be doing your first mock exam for at least one subject, ideally HL Maths or HL Sciences where time pressure is brutal.
Most schools run mock exams in January. These are your first realistic predictor of your final grade. Treat them as data, not judgement. After each mock, categorise every lost mark: was it content gap, mark scheme misread, or time management?
Submit final IAs by end of January. From this point, your internal assessment grades are locked in. Externals are now the only lever.
TOK essay is typically due to school in February. Polish it using your TOK teacher's feedback. The TOK presentation should already be done.
Use your mock results to identify the 3-4 weakest topics per subject. Spend February doing focused content review on those, not full-syllabus review. Studying things you already know well is procrastination dressed as productivity.
This is the past papers phase. Start with one full paper per subject per week under timed conditions. By end of March, you should have done at least 2-3 papers per subject. Focus on the most recent four years (May 2022 onwards) because syllabus changes mean older papers are not always relevant for new specs.
For each paper, do the paper untimed first to learn the question style. Then redo a fresh paper timed. Mark using the official mark scheme and examiner reports from the IBO. The examiner reports are where the real intel lives.
Increase to 2-3 full past papers per subject per week. By mid-April you should be hitting 8-10 papers per subject total. Track your scores. Watch for plateaus: when a subject stops improving, the bottleneck is usually mark scheme understanding, not content.
Spend at least one full Saturday doing a simulated exam day: Paper 1 in the morning, Paper 2 in the afternoon, with the official break length between them. Examiners report says nothing surprises high scorers because they have already lived the schedule.
No new content. Review your flashcard deck focusing on cards you keep getting wrong. Re-do FRQs from your weakest topics. Look at every mark you lost in past papers in the last month and pattern-match the mistakes.
The last 48 hours are for sleep, not study. Cramming the night before reduces working memory by 10-15% according to sleep researchers. You will lose more marks from fatigue than you gain from a final two hours of revision.
How to Split Hours Between HL and SL
This is where most IB students go wrong. They give equal hours per subject because that feels fair. It is not optimal.
Realistic weekly revision hours by month (combining all subjects):
| Month | Total weekly hours | HL share | SL share |
|---|---|---|---|
| Sept-Oct | 10-12 | ~60% | ~40% |
| Nov-Dec | 12-15 | ~60% | ~40% |
| Jan (mocks) | 18-22 | ~65% | ~35% |
| Feb | 15-18 | ~65% | ~35% |
| Mar (papers) | 22-28 | ~65% | ~35% |
| April | 30-35 | ~65% | ~35% |
| Final 2 weeks | 30-40 | varies | varies |
Hours adapted from published IB tutoring guides and student surveys; total reflects realistic capacity for students balancing CAS and sleep.
Inside each HL slot, weight your weakest subject the heaviest. If HL Chemistry is your stretch subject and HL English is comfortable, do not split HL time evenly. A 60/40 split inside HL towards the weaker subject is normal.
Try this now: Open your latest report card. Rank your six subjects from "comfortable 7 likely" to "struggling for a 5." Write the ranking on a sticky note. Every week, check that your study log shows the bottom two subjects got more hours than the top two. If not, you are revising the wrong things.
The Past Papers Workflow That Works
By March you should be running this loop every week per subject:
The IBO publishes subject reports and examiner commentary{target="_blank" rel="noopener noreferrer"} for every paper. These documents tell you the exact phrases markers want to see. Reading them is the single highest-leverage thing you can do during paper season.
Watch: IB Study Strategies in Action
Sometimes seeing how top scorers actually use their time is more useful than reading frameworks. Here are two videos worth watching this week.
HOW I GOT 45 POINTS IN IB! Tips & Tricks: Katie Tracy
Katie Tracy walks through habits and revision systems that helped her score the maximum 45.
Katie covers daily revision habits, IA strategy, and how she structured her DP2 calendar around the EE and IAs. Key insight: she started her EE in summer between DP1 and DP2, which freed her brain for content revision in November-December when most students are drowning in core requirements.
The 5-Step Method I Used to Score 43/45 in IB
A 5-step studying framework from a near-perfect IB scorer.
This video breaks down a repeatable 5-step study loop the creator used for every IB subject. Key insight: active recall paired with mark scheme analysis beat raw reading every single time. The mark scheme is the syllabus.
Subject-Specific IB Strategy (Quick Reference)
Each IB subject rewards a slightly different revision style. The high-level guidance:
| Subject group | What to revise from | Highest-leverage activity |
|---|---|---|
| Group 1 (Language A) | Set texts + Paper 1 unseens | Weekly timed Paper 1 unseen commentaries |
| Group 2 (Language B) | Vocab decks + past Paper 2 essays | Cloze flashcards + timed productive writing |
| Group 3 (History, Econ, Psych) | Subject guide + case studies | Source analysis drills + essay plans |
| Group 4 (Sciences) | Syllabus statements + data Q's | Flashcards for processes + past Paper 2 data Qs |
| Group 5 (Maths AA/AI) | Topic-by-topic problem sets | Mixed past paper sets + error log |
| Group 6 (Visual Arts, Theatre) | Process portfolio + IA prep | Studio time + reflective journal |
Compiled from IB subject guides and revision strategies published by IB Innovators, Lanterna Education, and U2 Tuition.
For HL Maths AA, the time bottleneck is Paper 3. Spend a disproportionate share of your past paper time on Paper 3 because it is the most novel question style and the one most students underprepare for.
For HL Sciences, the time bottleneck is Section B (data response and extended response). Most students drill Section A multiple choice and run out of time on Section B. Reverse that ratio in the final two months.
For HL History, the time bottleneck is Paper 3 (the regional, deep-detail paper). Most candidates spread effort evenly across Papers 1, 2, 3. The mark scheme rewards detail on Paper 3 more than the others, so weight it heavier.
The Science: Why Active Recall and Spacing Beat Re-Reading
This is not just opinion. The IB rewards retrieval-based learning more than any other major qualification because Paper 2 and Paper 3 questions cannot be answered by recognition alone. You have to produce the content from memory under time pressure.
Roediger and Karpicke (2006) compared students who repeatedly re-read a text against students who tested themselves. One week later, the testing group remembered 50% more. Karpicke and Blunt (2011) ran the same comparison with concept mapping and found self-quizzing still won, even on inference questions.
For IB specifically, this means:
- Re-reading the textbook is the worst use of revision time. It feels productive but produces low retention.
- Mind maps from scratch beat copying mind maps. Generation is the active part.
- Self-tests using past papers beat reading model answers. Producing the answer is the skill.
Recognition is not recall. The IB exam asks you to produce answers, not recognise them. Every time you re-read a page, you are training recognition, not the skill you will be tested on.
Cepeda et al. (2006) reviewed 254 studies on spaced repetition (over 14,000 participants) and concluded that spaced practice produced significantly better long-term retention than massed practice across every age group and content type tested. For IB, this means short daily review sessions over 9 months crush "intensive revision" in April.
Spaced repetition only works if you actually space the reviews. The simplest way to do that is to let software handle the schedule. Spaced repetition apps compute the optimal review interval per card based on how well you remembered it last time.
How Notesmakr Helps You Apply This Plan
Notesmakr is a note maker built around exactly this kind of multi-subject, multi-deadline workload. The relevant features for IB students:
Free features (every IB student should use these)
- Cloze deletion flashcards with Diminishing Cues for IB vocabulary, definitions, dates, and formulas. The progressive letter hints help when you blank.
- Anki .apkg import so you can bring popular IB decks like IB Crackers community Anki decks straight into Notesmakr without re-creating them. (50MB max file size.)
- Spaced repetition (SM-2 algorithm) schedules your review intervals automatically. Study a card. Mark how well you remembered it. It comes back at the right time, not too soon and not too late.
- Manual flashcards and handwriting notes for IB subjects where you want to write longhand (often the case for HL Maths working).
Paid features (Scholar / Scholar+)
These features require a paid plan because they call AI generation backends:
- AI flashcards from PDF subject guides (generate cards from a PDF). Drop in your IB subject guide PDF or class notes. The AI builds a deck without you typing every card. Saves 10+ hours per subject.
- AI quiz maker (create a quiz) for past paper question generation in the same style as IB markers. Useful when you have exhausted real past papers and want extra practice.
- AI mind map generator (build a mind map) for visualising connections in HL History or HL Biology where systems matter more than facts.
- Note simplification (Feynman style) for TOK essay prep, where explaining ideas in plain language is the entire grading rubric.
For IB-specific decks: Search "IB Crackers" or "Quizlet IB" Anki decks online (the IB community has built large free libraries). Import the .apkg file into Notesmakr free tier. You now have a starting deck, with Notesmakr's spaced repetition and cloze hint features layered on top.
Free tier has a 5-note limit for AI features. Cloze cards, manual cards, .apkg import, and SM-2 scheduling are unlimited on the free plan.
Common IB Study Mistakes to Avoid
Mistake 1: Treating IAs as last-minute coursework. IAs are 20-30% of each subject grade. Score a 5 on an IA in a subject where you needed a 7 and you have made the exam path much harder. The fix: Have all six IAs finished in first draft form by December of DP2, with one revision cycle complete before January submission.
Mistake 2: Doing past papers untimed forever. Untimed is fine for content review on your first attempt at a paper. After that, every subsequent paper must be timed. The IB tests speed alongside content. The fix: From March onwards, every paper attempt is under exam conditions: timed, no phone, full break length between papers if doing back-to-back.
Mistake 3: Ignoring examiner reports. The IBO publishes a detailed report after every exam session telling you the most common mistakes students made. This is free, official intel. Most students never open one. The fix: Read the examiner report for every past paper you do. Highlight the recurring patterns. Those are the markers' pet peeves you must avoid.
Mistake 4: Studying HL and SL equally. HL takes more time. If you give HL Chemistry the same hours as SL Spanish, you will underprepare for HL Chemistry. The fix: Use the 60/40 to 65/35 HL-weighted split shown above and review the split each month.
Mistake 5: Cramming for mocks. Mocks are diagnostic, not predictive. The point is to find your weaknesses 3-4 months before the real thing. Cramming a week before mocks hides the gaps you need to find. The fix: Sit mocks honestly. Use the result to redirect February-March revision toward your actual weak spots.
Mistake 6: Reusing study methods that worked at GCSE/IGCSE/MYP. IB rewards depth and synthesis. Re-reading and highlighting may have been enough at MYP. They are not at DP. The fix: Switch to retrieval-based methods (flashcards, past papers, self-explanation). Re-reading is at the bottom of the evidence-based effectiveness rankings Dunlosky et al. (2013) produced.
Try this now: Pick your weakest subject. Open the most recent published examiner report on the IBO site. Find the section called "candidate performance against each question." Read it for 10 minutes. Write down the three most common mistakes the examiner flagged. Those are now the three things you are working to avoid in April.

Frequently Asked Questions
How many hours should I study for IB exams per week?
In DP2, plan for 10-12 hours per week in September-October, scaling to 22-28 hours per week in March (past papers phase), and 30-35 hours per week in April. Weight HL subjects roughly 60-65% of total hours because HL content is deeper and exams have an extra paper. Consistency beats intensity. Daily review across 9 months crushes a March panic.
When should I start studying for IB exams?
Start structured revision in September of your DP2 year, eight to nine months before May exams. Use summer between DP1 and DP2 for the Extended Essay first draft and any HL textbook reading you can get ahead on. By the time exams arrive, you should have completed 8-10 full past papers per subject, all six IAs, the EE, and TOK essay.
What is the difference between HL and SL in IB?
HL (Higher Level) subjects cover roughly 240 teaching hours of content and typically include an extra exam paper (Paper 3) testing deeper application. SL (Standard Level) covers about 150 teaching hours with usually two papers instead of three. HL is required for three of your six IB subjects. Most universities care about your HL grades more than SL when assessing course fit.
How do I score a 45 in IB?
Scoring the maximum 45 requires 7s in all six subjects plus 3 bonus points from EE and TOK combined. Roughly 0.2% of IB candidates achieve 45 each session. The practical path: lock IAs at 7-level early, submit a strong EE, master past papers via the diagnostic loop (mark scheme + examiner reports), and weight revision toward your weakest subjects until they catch up.
Is the IB harder than AP exams?
The IB is broader (6 subjects + 3 core components over 2 years), while AP is modular (you can take 1-12 AP exams independently). IB demands more sustained workload and writing, especially for the EE and TOK. AP demands more depth in single subjects with shorter timeframes. Most US universities accept both, but IB Diploma graduates often receive more transfer credit.
What is the most effective IB revision method?
Active recall via past papers and spaced repetition flashcards. Roediger and Karpicke (2006) showed self-testing produces 50% better retention than re-reading. For IB specifically, do timed past papers from March onwards, mark them against the official mark scheme, and read the IBO examiner reports. Pair this with daily flashcard reviews so content does not decay between revision blocks.
