The CBSE Class 12 Mathematics exam is scheduled for March 8, 2025. With limited time left, effective revision is crucial. The paper follows a structured format, covering Calculus, Algebra, Vectors & 3D Geometry, and Probability as core sections. Here’s how students can maximize their revision in the final 24 hours.
Key Topics to Prioritize
Calculus:
- Continuity & Differentiability – Differentiability at a point, basic theorems
- Applications of Derivatives – Tangents & Normals, Rate of Change, Increasing & Decreasing functions
- Integrals & Applications – Definite integrals properties, Area under curves
- Differential Equations – Formation and solutions of first-order equations
Algebra:
- Matrices – Adjoint and Inverse
- Determinants – Properties and applications
Vectors & 3D Geometry (14 Marks):
- Dot product, Cross product
- Equations of planes
- Shortest distance between two skew lines
Probability:
- Conditional probability, Bayes’ theorem
- Probability distributions
Linear Programming:
- Graphical solutions of linear programming problems
Last 24-Hour Revision Plan
- Revise formulas & theorems – Keep a single sheet of key formulas handy.
- Go through NCERT examples – Many board questions follow NCERT patterns.
- Solve a past paper under exam conditions – Simulate the test experience.
- Review common mistakes – Avoid repeating errors from mock tests.
- Practice a mix of question types – Cover one question from each unit for a final refresher.
Avoid: Learning new concepts, spending too long on one topic, or studying late at night.
How to Handle Difficult Questions
- Read carefully – Misinterpretation leads to mistakes.
- Break the question into parts – Identify given data and required formulas.
- Use a stepwise approach – Partial marks are awarded for correct steps.
- Move on if stuck – Attempt easier questions first.
- Recheck calculations – Reserve 15 minutes for error correction.
Final Exam Tips
- Get enough sleep – A well-rested mind enhances accuracy and recall.
- Arrive early at the exam center – Reduce stress and settle in.
- Attempt familiar questions first – Build confidence before tackling tough ones.
- Use proper notation – Clear steps and labelled diagrams improve scoring.
- Save 10-15 minutes for revision – Identify and correct mistakes.
With structured problem-solving and a calm approach, students can confidently aim for a high score. Trust your preparation and enter the exam hall with focus and confidence.
