However, the reality is that Maths is one of the most scoring subjects if you focus on the right topics. Instead of solving everything randomly, you need to concentrate on high-weightage topics, repeated questions, and core concepts that are frequently tested.
This guide is designed to help you revise smartly, not just extensively. If followed properly, you can comfortably target 60–80+ marks even with limited time.
Why Focused Revision Works in Maths
Mathematics is not about studying more—it is about practicing the right questions repeatedly.
In CBSE board exams:
- Many questions are repeated with slight variations
- Certain problem types appear almost every year
- Concept-based and application-based questions dominate
- PYQs (Previous Year Questions) form a strong base of the paper
So instead of solving every question in your textbook, your focus should be:
- Important formulas and identities
- Repeated PYQs and sample questions
- Word problems and case-based questions
- Numerical accuracy and step presentation
This strategy saves time, builds confidence, and ensures maximum marks.
Chapter-Wise Important Topics
Below is a detailed and expanded breakdown of all chapters with key focus areas, formulas, and expected question patterns.

Clear understanding ensures quick solving.
Triangles
This chapter is theorem-based and often includes proofs.
Key topics:
- Basic Proportionality Theorem (BPT)
- Similar triangles
- Ratio-based problems
BPT concept:
- A line parallel to one side divides the other sides proportionally
Practice writing proper steps for proof questions.
Circles
Small chapter but important for theory questions.
Key theorems:
- Tangents from an external point are equal
- Radius is perpendicular to tangent
You may also get application-based questions involving quadrilaterals.
Trigonometry
A very important and scoring chapter.
Key topics:
- Trigonometric identities
- Standard angle values
- Proof-based questions
Key values:
- sin 30° = 1/2
- cos 60° = 1/2
- tan 45° = 1
Regular practice of identities is essential.
Applications of Trigonometry
Real-life application chapter.

Tip:
- Always draw a diagram before solving to avoid mistakes
Areas Related to Circles
Formula-based chapter with application questions.
Important formulas:
| Concept | Formula |
| Area of sector | (θ/360) × πr² |
| Arc length | (θ/360) × 2πr |
Practice diagram-based questions like Olympic rings.
Surface Areas and Volumes
Application-based chapter with high weightage.
Important topics:
- Combination of solids
- Removing/scooping shapes
These questions usually carry 4–6 marks and require careful calculations.
Statistics
Scoring chapter with direct formulas.
Important topics:
- Mean, median, mode
