Maths is nothing without formulas.
Students who score 100 write formulas daily.
Make a small formula notebook. Keep it on your table. Revise 2–3 pages every day.
Important formula areas:
- Derivatives
- Integrals

4. Understand Concepts in the Easiest Way
If you depend only on mugging, you will forget.
But when you understand why something works, you remember it for years.
For example:
- Why derivative means rate of change
- Why determinant changes when you swap rows
- Why integration feels like adding small pieces
Simple understanding leads to full marks. You don’t need big words. Just understand the idea.
5. Make a Weekly Practice Plan
Every topper follows a small routine. Nothing fancy. Just a fixed plan.
Here’s a simple one that works:
Daily (1 to 1.5 hours)
- Do 10 sums from old chapters
- Do 1–2 new concepts from the current chapter
- Revise 5–6 formulas
Weekly
- Solve one mixed chapter test
- Re-check mistakes
- Fix weak areas
When you practice like this, you automatically move closer to scoring 100.
6. Solve Sample Papers (Latest CBSE Pattern)
Solving sample papers helps you understand:
- paper pattern
- difficulty level
- speed
- writing steps
- time management
Moreover, sample papers show you where you make silly mistakes. When you solve 8–10 papers, your brain becomes exam-ready.

Furthermore, avoid writing too long steps. Keep them clean and simple.
9. Focus on Important Chapters That Carry More Marks
Some chapters are easy and scoring.
Some are slightly longer but carry good weight.

- Linear Programming
- Relations & Functions
- Inverse Trigo
High-weightage chapters:
- Integrals
- Applications of Integrals
- Differential Equations

- 3D Geometry
Mastering these gives you a strong base to score 90+ easily. Then with a little push, you reach 100.
10. Avoid These Common Mistakes
Many students lose 5–15 marks due to very small mistakes.
Avoid them:
- writing wrong sign ( + instead of – )
- doing long steps too fast
- forgetting formulas
- not checking calculation
- leaving 1–2 questions due to fear
- skipping NCERT Miscellaneous
Moreover, don’t use shortcuts in the first attempt. Understand fully, then shorten steps.
11. Prepare a 1-Month Before-Exam Strategy
Here’s what should happen in the last month:
Week 1
Revise NCERT fully
Solve 2 sample papers
Week 2
Revise formulas daily
Solve 3 sample papers
Fix mistakes
Week 3
Solve at least 4–5 previous year papers
Focus on weak chapters
Week 4
Light revision
Practice small sums
Fix silly mistakes
Sleep well
Indeed, students who revise lightly in the last week score higher than those who study in panic.
12. What to Do One Day Before the Maths Board Exam
This day is important.
Do this:
- revise formulas 2–3 times
- do not solve new questions
- quickly look at examples
- sleep early
- keep your admit card ready
Moreover, stay calm. A relaxed mind remembers everything better.
13. How to Attempt the Maths Paper to Score Full Marks
Follow this simple pattern:
Step 1: Start with easy questions
This builds confidence.
Step 2: Don’t rush
Write slowly and neatly.
Step 3: Leave 15 minutes at the end
Use this time to check signs, formulas, last steps.
Step 4: Underline answers
Makes checking easy.
Step 5: Keep handwriting clear
You don’t need creative writing. Just clean writing. Moreover, solve rough work on the last page only.
