How Many Hours Should You Study for IB Physics?

Aim for 4-6 hours a week at SL and 6-8 at HL outside class time, then double that in the final eight weeks before exams. According to the IB, DP subjects require a minimum 150 teaching hours at SL and 240 at HL over two years — your independent study should roughly match that ratio.

SL students typically need 4-6 hours a week; HL students need 6-8, mostly because of the extra option-free HL-only topics (Engineering Physics, Astrophysics or similar depth in Relativity) and harder Paper 3 data-analysis questions. Both figures roughly double in the two months before final exams.

Yes — HL Physics is generally considered the most maths-heavy of the three DP sciences, because Paper 3's data-based question and the extended core topics (like Relativity and Quantum Physics) demand calculus-adjacent reasoning that HL Chemistry and Biology don't ask for in the same depth.

IB Physics is one of the harder DP sciences, mainly because of its maths demands — vectors, exponentials, and graphical analysis appear from the first term. HL is genuinely tough; SL is manageable if you keep on top of formulae and practical write-ups rather than leaving them until study leave.

IB doesn't publish a fixed annual figure that stays constant, but Physics HL 7s typically sit in the 8-12% range in recent examination sessions, similar to Chemistry HL and slightly below Maths AA HL. SL 7 rates tend to run a little higher, closer to 12-15%.

Consistent past-paper practice under timed conditions is the single biggest lever — more than re-reading notes. Students who hit a 7 usually complete 15-20 full past papers across both levels before finals, review every mark lost against the mark scheme, and keep a running list of formulae mistakes.

Paper 1 is multiple-choice (with a data-based/short-answer variant at HL), Paper 2 is extended short-answer and structured problems covering the whole syllabus, and Paper 3 tests the option-free data-analysis and one syllabus option topic. According to the IB, first exams for the current Physics guide were in 2025.

More than most students expect. Expect algebraic rearrangement, trigonometry, logarithms and exponentials constantly, and at HL some basic calculus intuition for topics like Simple Harmonic Motion and capacitor discharge — though the formula booklet gives you the final equations, not the derivations.

Mechanics and Electricity & Magnetism carry the most marks across Papers 1 and 2 at both levels, so revise those first if you're behind. Then prioritise whichever option topic your school taught (Paper 3), since it's a guaranteed, self-contained block of marks you can master quickly.

HL suits students aiming for engineering, physical sciences or physics-adjacent degrees, and it pairs naturally with Maths AA HL. SL suits students who need Physics for a broader science background but won't use it directly at university — the workload difference (roughly 90 extra teaching hours) is real and worth weighing against your child's other five subjects.

Yes — most competitive engineering programmes either require or strongly prefer HL Physics alongside HL Maths, since it demonstrates the applied maths and mechanics fluency universities assume on entry. Some universities will accept SL Physics with HL Maths, but check specific course entry requirements before finalising subject choices.

Self-study resources — revision guides, topical worksheets, and mock exam packs — typically cost far less than any one-to-one tuition arrangement, and let your child practise past-paper technique independently at their own pace. On RevisionPrep, students can work through Revision Notes and Topical Worksheets built around the current Physics guide without a recurring session cost.
