How to Score 90+ in Maths in Just 1 Day: The Ultimate Last-Minute CBSE Class 10 Board Exam Guide

If your CBSE Class 10 Maths exam is tomorrow, take a deep breath. One day is not enough to learn everything from scratch - but it is absolutely enough to revise smartly, strengthen scoring areas, and improve accuracy.

Scoring 90+ in Maths is not about being a genius. It’s about:

• Strong formula recall
• Step-wise presentation
• Smart question selection
• Avoiding silly mistakes

This guide is designed using the latest CBSE paper pattern, marking scheme trends, and common student performance analysis to help you focus only on what matters in the final 24 hours.

CBSE Class 10 Maths Exam Tomorrow? Don’t Panic – Here’s Your 1-Day Strategy

The biggest mistake students make one day before the CBSE board exam is panic-studying everything. That lowers confidence and increases confusion.

Instead:

• Revise what you already know
• Focus on high-weightage chapters
• Practice most expected questions
• Strengthen formulas and theorems

24-Hour Study Plan to Score 90+ in CBSE Class 10 Maths

Step 1- Revise High-Weightage Chapters First (Important Questions Focus)

Start with scoring chapters:

• Algebra (Quadratic Equations, AP, Pair of Linear Equations)
• Trigonometry (Identities + Heights & Distances)
• Mensuration (Surface Areas and Volumes)
• Statistics & Probability

Focus on:

• CBSE Class 10 Maths important questions chapter-wise
• 4 and 5 mark numericals
• Case study based questions

Do not start new concepts. Revise solved examples from NCERT and previous board-type questions.

Step 2 - Solve One CBSE Class 10 Maths Sample Paper

Take one latest sample paper and solve it within 3 hours.

While solving:

• Attempt easy questions first
• Show complete steps
• Write formulas before solving

After finishing:

• Check answers using marking scheme
• Identify repeated mistakes
• Revise those specific concepts

This improves time management and confidence.

Step 3 - Quick Revision of Important Formulas for Class 10 Maths

Formula recall can directly increase your score by 10–15 marks. Write these once for better memory retention:

Algebra Formulas

• Quadratic Formula: x = (-b ± √(b² – 4ac)) / 2a
• Discriminant: D = b² – 4ac
• AP nth term: an = a + (n – 1)d
• AP sum: Sn = n/2 [2a + (n – 1)d]

Trigonometry Formulas

• sin²A + cos²A = 1
• 1 + tan²A = sec²A
• 1 + cot²A = cosec²A

Standard values (0°, 30°, 45°, 60°, 90°) must be perfect.

Mensuration Formulas

• Volume of cone = 1/3 πr²h
• Volume of sphere = 4/3 πr³
• Frustum volume = 1/3 πh (R² + r² + Rr)

Statistics & Probability

• Mean (Step deviation method)
• Probability = Favorable outcomes / Total outcomes

Revise these carefully. Many students lose marks simply because they forget formulas.

Step 4 - Practice Most Expected Questions in Maths Board Exam

Focus especially on:

• Quadratic equation word problems
• Pair of linear equations case study
• Surface areas and volumes mixed solid problems
• Statistics step deviation method
• Probability basic questions

Practicing 10–15 important questions per weak chapter is enough.

Important Formulas List for Class 10 Maths Board Exam (Quick Revision)

Make a single-page formula sheet including:

• Quadratic formula
• AP formulas
• Trigonometric identities
• Surface area and volume formulas
• Mean formulas
• Probability formula

Revise this sheet before sleeping and once in the morning.

Common Mistakes to Avoid in CBSE Class 10 Maths Board Exam

Avoid these common errors:

1. Starting new chapters one day before exam
2. Skipping steps in 4–5 mark questions
3. Not writing formulas before solving
4. Forgetting units in mensuration
5. Poor time management
6. Leaving case study questions for last without reading carefully
7. Calculation mistakes due to rushing

Board exam marking gives step-wise marks. Even if the final answer is wrong, correct steps can fetch partial marks.

Exam Hall Strategy to Score 90+ in Maths

• Use first 15 minutes to read paper calmly
• Attempt Section A and easy questions first
• Do not spend more than 5–6 minutes on one 2-mark question
• Show all rough work clearly
• Draw neat diagrams in Geometry
• Keep last 10 minutes for checking calculations

Accuracy matters more than speed.

Final Night Revision Tips for CBSE Class 10 Maths

• Revise formulas once
• Go through solved examples
• Do not discuss difficult questions with friends
• Sleep at least 6–7 hours

A calm mind performs better than a stressed one.
