How to Use This Resource
Use this complete guide after finishing textbook reading. It is designed for Class 9 students who need organised revision without leaving the official Samacheer Kalvi textbook.
Coverage
- Term 1 revision (Set Language, Real Numbers)
- Term 2 revision (Algebra, Geometry, Coordinate Geometry)
- Term 3 revision (Trigonometry, Mensuration, Statistics, Probability)
- Textbook exercise practice for all chapters
- Important questions by mark type
- Common mistake correction
- Final exam readiness
Practice Method
1. Pick one chapter. 2. Revise the key points and formulae. 3. Write answers and proofs without looking at the guide. 4. Correct with textbook keywords and formulas. 5. Repeat weak questions after two days.

Formula Bank Summary
- Set Language: n(A ∪ B) = n(A) + n(B) − n(A ∩ B)
- Real Numbers: Laws of surds and exponents
- Algebra: Remainder = p(a); Factor if p(a) = 0
- Geometry: All congruence criteria; circle theorems
- Coordinate Geometry: Distance, midpoint, section formulas
- Trigonometry: Three identities; standard values table
- Mensuration: LSA, TSA, Volume for all 5 solids
- Statistics: Mean = Σfx/Σf; Median and Mode formulas
- Probability: P(E) = n(E)/n(S); 0 ≤ P(E) ≤ 1
Textbook Solutions Workflow
1. Complete textbook reading before using guide answers. 2. Write exercise answers in a notebook. 3. Check missing steps, formulas, units, or reasoning. 4. Rewrite weak answers once after correction. 5. Keep one page for mistakes from every chapter.
