STUDY GUIDE
How to Study IB Math
Most students study IB Math the wrong way, rereading notes, copying worked examples, hoping things "click" the night before a test. This guide covers what actually works: from weekly habits to past paper strategy to exam-day technique.
THE FOUNDATION
The Truth About Studying Math
Math is not a subject you can learn by reading. You can read a perfect explanation of how to solve a differential equation, understand every word, and still be unable to do it yourself on an exam. This is not a failure of intelligence, it's a failure of practice method.
The only way to learn mathematics is by doing mathematics. Struggling with a problem, getting stuck, finding the gap in your understanding, and then closing that gap, that is what builds real mathematical ability. Watching someone else solve it does not.
"Every student can succeed in math. They just need the right support, the right tools, and someone who believes in their potential."
, Patricia AkaoThe good news: IB Math exams are highly predictable. The same types of questions appear year after year. If you know how to work through them systematically, you can succeed at any level.
THE SYSTEM
A 5-Step Study System That Works
-
1
Diagnose Your Gaps First
Before doing anything else, find out exactly which topics you struggle with. Do a topic-by-topic audit: go through past paper questions by topic, mark them honestly, and list where you lose marks most. This is your study priority list. Don't study randomly, study strategically.
-
2
Learn by Doing, Not Watching
For each weak topic, attempt the problem first, even if you don't know how. Struggle with it for 5–10 minutes. Then check the solution or ask for help. This active struggle is what creates memory. Students who watch YouTube solutions without attempting the problem first rarely retain the method.
- Attempt before looking at the mark scheme
- When you're stuck, write down what you tried and where you stopped
- After checking, redo the problem from scratch without looking
-
3
Do Past Papers Under Timed Conditions
Past papers are the most valuable revision tool for IB Math. Not doing them, but doing them timed, on paper, without checking answers mid-way. The IB exam is a time-pressured exercise. Practicing under those conditions is what prepares you for them.
- Start past papers 8 weeks before exams
- Do the full paper timed, don't skip hard questions
- Mark strictly using the official mark scheme
- Spend more time on your review than on the paper itself
-
4
Review Every Single Mark Scheme
The biggest mistake students make with past papers: doing them and checking only their score. You need to understand every mark, including the ones you got right by accident, and the ones you almost got. The mark scheme shows you exactly what the examiner wants. Study it.
- Annotate the mark scheme for every question you didn't fully understand
- Keep an error log: write what went wrong and the correct approach
- Redo questions you got wrong 2–3 days later without looking at notes
-

Review Consistently, Not in Bursts
IB Math rewards consistent weekly effort far more than intense cramming. A student who studies 5 hours spread across a week retains more than one who studies 10 hours the night before. Build a weekly routine early in Year 2, and stick to it even when other subjects demand attention.
WEEKLY HABITS
A Realistic Weekly Routine
These times are a starting point, adjust based on your level (HL needs more) and where you are in the year.
After Each Class
Write a 3-line summary of what was covered. Attempt 2–3 practice questions on the new topic while it's fresh. Flag anything you don't understand so you can ask next lesson, not 3 weeks later.
Twice a Week
45–60 minutes of focused practice. Pick 2 topics: one current and one you've already covered but want to reinforce. Mixed practice, not just the new stuff, is what builds lasting retention.
Once a Month
Do a full past paper under timed exam conditions. Mark it strictly. Identify your 3 biggest error categories. Spend the following week specifically targeting those areas.
Keep an Error Log
A simple notebook page: the date, the question, what went wrong, and the correct method. Review it monthly. Students who do this consistently see the same mistakes disappear within a few weeks.
EXAM COUNTDOWN
What to Do With 12 Weeks to Go
Work through every topic systematically. Use your IB syllabus as a checklist. For each topic: attempt past paper questions by topic (Revision Village is useful here), identify gaps, and close them with targeted practice.
One full past paper every 4–5 days. Mark strictly using official mark schemes. Review carefully. Keep your error log updated. Pay attention to command terms, losing marks on "show that" or "justify" is avoidable.
Revisit every topic where you're still dropping marks. Focus on method marks, even when the final answer is wrong, showing the right process earns points. Practice writing clearly: examiners can only mark what they can read.
Review your formula booklet and any formulas NOT in it. Go through your error log. Do one more paper early in the week. Then rest. Sleep and food on exam day matter more than a last-minute cramming session.
COMMON MISTAKES
5 Myths That Keep Students Stuck
-
MYTH
Re-reading notes and textbooks counts as studying math.
TRUTH
Passive reading builds familiarity, it does not build skill. You need to solve problems, make mistakes, and correct them. Recognising a method when you see it is not the same as being able to apply it under exam pressure.
-
MYTH
If I do enough past papers, I'll be fine.
TRUTH
Past papers are only useful if you review them properly. Doing 10 papers and checking only your score teaches you very little. The learning happens in the review, understanding every mark, analysing every mistake, and correcting errors before they become habits.
-
MYTH
I need to understand everything before I practice.
TRUTH
Attempting problems, even when you're unsure, is how understanding develops. You learn more from a failed attempt followed by a clear explanation than from watching ten perfect worked examples. Struggle is productive.
-
MYTH
IB Math is too hard, I'm just not a math person.
TRUTH
"Math people" are not born, they're built through practice and the right support. Every student I have ever worked with who committed to consistent practice improved. The IB Math grade boundaries are fixed; the path to them is through skill, not aptitude.
-
MYTH
I'll start seriously revising 4 weeks before exams.
TRUTH
Four weeks is not enough time to close large gaps. The students who improve 2–3 grade levels are the ones who start building habits 6–12 months out. Early, consistent effort compounds. Last-minute revision can only consolidate what you already know, it cannot build new understanding.
COURSE-SPECIFIC
Key Differences by Course
For both courses: read the question twice before writing anything. Many marks are lost not because students don't know the mathematics, but because they answer a question they think was asked, rather than the one that was.
EXAM DAY
Exam Day Checklist
- GDC with charged batteries (and a spare set)
- Formula booklet is provided, focus on knowing how to use it, not memorising it
- Read every question fully before starting to write
- Show all working clearly, method marks are always available
- If stuck, move on and return, don't lose time on one question
- Check your answer makes sense in context (negative time, probability > 1, etc.)
- Write answers in the correct form (exact vs decimal, degrees vs radians)
- AA Paper 1: put the GDC away, using it can invalidate your answer
- AI Papers: know your statistical tests cold, which test applies to which scenario
- Review your work in any remaining time, start from the last question back
COMMON QUESTIONS
Study FAQs
How many past papers should I do?
Aim for at least 5 full past paper sets under timed conditions before the exam. Earlier in the year, use topic-specific question banks to build core skills. Switch to full papers 8 weeks out. Quality of review matters more than quantity of papers, doing 3 papers well beats doing 10 quickly.
How long does it take to improve from a 4 to a 6?
With consistent weekly study, most students move 1–2 grade levels in 3–6 months. The biggest gains come from understanding exactly what went wrong in past assessments and then practicing precisely those areas. Reviewing completed work carefully, not just doing more practice, is where real improvement happens.
Should I memorise formulas?
You receive a formula booklet in every paper. But you still need to know which formula to use when. Memorise what's NOT in the booklet (common derivative rules, trig identities, standard distribution shapes). For everything in the booklet, focus on understanding and application rather than rote memorisation.
Is there a difference in how to study for HL vs SL?
The approach is the same, but the volume and depth of content is higher at HL. HL students should start their full revision 2–3 weeks earlier than SL students. For HL specifically: build a strong foundation in HL-only topics early, these tend to appear heavily in Paper 2/3 and are easy to neglect.
