CSCA Topic Breakdown: Chapter Percentages by Subject
See Math, Physics and Chemistry chapter percentages and question counts, based on PrepPals’ analysis of recalled March 2026 CSCA questions.

Which chapters take the largest share?
From PrepPals’ analysis of recalled March 2026 CSCA questions, the largest chapter group in each subject is:[4][5][6]
Mathematics
23.4%Trigonometry
Physics
26.7%Kinematics
Chemistry
23.4%Classification & stoichiometry
Other sittings we have analysed show a similar balance, with a few questions’ difference per chapter.

Use topic share and your own errors together
Use the chapter shares with your latest answers: prioritise a larger topic where your method is still unreliable.

Questions students ask about CSCA topic weighting
Which topics carry the most weight in CSCA Mathematics?
Trigonometry has the largest share in PrepPals’ March 2026 analysis: 23.4%.
- Sets, inequalities and basic algebra account for 14.9%; coordinate geometry also accounts for 14.9%.
- Use the Mathematics pie chart for all eight chapter groups and their question allocations.
Which topics carry the most weight in CSCA Physics?
Kinematics leads at 26.7% in the March 2026 analysis.
- Newton’s laws and forces, work/energy/momentum, and electric fields/circuits each account for 15.6%.
- The full Physics syllabus still includes topics such as modern physics that are not shown as a separate slice.
Which topics carry the most weight in CSCA Chemistry?
Classification and stoichiometry lead at 23.4% in the March 2026 analysis.
- Atomic structure, bonding and periodic trends follow at 19.1%; acids, bases, salts and solutions account for 14.9%.
- Use the Chemistry pie chart to compare all seven chapter groups.
Where do these CSCA chapter percentages come from?
They come from the PrepPals Academic Team’s own analysis of recalled March 2026 CSCA questions.
- The team grouped recalled questions by chapter for Mathematics, Physics and Chemistry.
- These are first-party exam observations; the official syllabuses define the examinable scope.
How many questions are allocated to each CSCA chapter?
The chapter counts beside each subject’s pie chart add up to 48 questions.
- They are whole-number allocations converted from our March 2026 chapter percentages, with the method recorded in Sources.
- They show the balance of a 48-question paper; another sitting may differ by a few questions per chapter.
Does the CSCA topic distribution change between exam dates?
The overall chapter balance has been similar across the sittings PrepPals has analysed.
- This page uses March 2026 as the example; individual chapters may have a few more or fewer questions in another sitting.
- Use the broad pattern to plan practice while maintaining full syllabus coverage.
Can I skip CSCA chapters with a small share?
No. A smaller share does not remove a topic from the exam scope.
- Prioritise recurring errors in larger chapters, but keep smaller chapters in mixed practice.
- For a short review window, the final two-day subject checklists help you choose manageable tasks.
How should I use the CSCA topic breakdown to plan revision?
Combine chapter share with your own recent performance.
- Start with a familiar, larger-share topic where errors keep returning; repair one failed step and retry it without notes.
- Use the 21-day study plan to spread practice and later checks across the time you have.
