How Many Hours Should You Study for IB Maths?

Plan for 4-6 hours a week outside class for Maths AA/AI SL, and 6-8 hours for HL, rising to 15-20 hours a week in the final two months before exams. According to the IB Mathematics guide, SL is built on 150 recommended teaching hours and HL on 240 — self-study should scale with that gap.

For most students, 3-5 hours a week is the baseline for SL and 5-7 hours for HL, split across at least three separate sessions rather than one long block. Saturday-morning cramming doesn't build the pattern recognition IB Maths papers actually test — little and often wins in every class I've tracked.

Expect 15-20 hours a week on Maths alone during study leave if it's a weak subject, or 10-12 hours if it's already solid — roughly 2-3 hours a day. That time should be split between full timed past papers and targeted topic review, not re-reading notes.

Yes — one hour a day (about 7 hours a week) is usually enough for SL students to reach a 5 or 6, provided it's focused practice rather than watching worked examples. It's rarely enough for HL, or for a 7 at SL — those students typically need closer to 90 minutes a day across the two years.

Students who land a 7 in Maths AA HL almost always rework past papers under strict timed conditions, keep a running log of exact mistakes rather than just marks, and revisit weak topics weekly rather than once a term. Grade 7 boundaries have typically sat around 75-80% of raw marks across recent sessions.

The single highest-return method is timed past-paper practice, marked against the actual IB markscheme rather than just checking final answers. I tell every student I teach to log each error under one of four buckets — arithmetic slip, wrong method, misread question, or concept gap — because that log tells you exactly where the next hour of revision should go.

Aim for 15-20 full past papers across the two years, with at least 6-8 done under strict timed conditions in the final three months. That's enough exposure to the range of problem-solving and interpretation questions the IB sets across Paper 1, Paper 2, and — for HL — the extended-response Paper 3.

Daily, shorter sessions beat cramming every time in Maths, because the subject is cumulative — a shaky grip on trigonometric identities in Year 1 resurfaces in HL calculus proofs in Year 2. A single three-hour cram session the week before exams can't rebuild two years of gaps; four 45-minute sessions a week across the course can.

Maths AA is more abstract and proof-heavy; Maths AI leans on modelling, statistics and technology — neither is objectively harder, but AA HL typically demands more weekly hours because of its calculus and proof content. Choosing AA to look impressive on a university application, without the algebra background, usually costs an extra 2-3 hours a week just to keep pace.

According to the IB Mathematics guide, SL courses are built around 150 recommended teaching hours and HL courses around 240 hours across the two years. HL isn't 'SL plus a bit extra' — it's roughly 90 more classroom hours plus a third exam paper, and self-study time should scale with that difference.

Calculus (differentiation and integration) and Statistics/Probability consistently eat the most revision hours because they build on several prior topics and appear across multiple exam papers. Vectors, and complex numbers at HL, are the next biggest time-sinks — students often underrate them until a non-routine question turns up in Paper 2.

Choose Maths AI if your child is heading towards social sciences, business or design and is more comfortable with applied, technology-based problems; choose Maths AA for engineering, physics, pure maths or computer science routes needing strong algebraic and calculus grounding. Neither course caps university options at SL, but many quantitative degrees do specify AA HL specifically.

HL Maths is worth the roughly 90 extra teaching hours and 2-3 extra self-study hours a week only if your child needs it for a specific degree — engineering, physics, actuarial science — or is genuinely strong in the subject and aiming for top marks. If neither applies, SL frees up hours that often lift grades elsewhere across the Diploma.

The resources that save real study time are built around exam-style practice rather than re-teaching content from scratch: a topic-sorted question bank, concise Revision Notes per topic, and full timed Mock Papers with markschemes. Well-organised Topical Worksheets for Maths AA and AI let revision hours go straight into solving problems rather than hunting for suitable ones.
