How to Use This Syllabus
Prioritise by marks
Use the unit-wise distribution above. Focus first on units with 20+ marks — they give the best return on study time.
Skip deleted topics
CBSE will not ask deleted topics in the board exam. Don't waste time on them — use that time for NCERT exercises instead.
Know the paper pattern
Section E (Case Study) has new-format questions many students ignore. Practise these separately — they're easy marks.
You know the syllabus. Now practise it.
ClearSteps gives you chapter-wise mock tests aligned to the exact CBSE Class 8 Mathematics syllabus, with AI evaluation against the official marking scheme.
