How to Score 90%+ in CBSE Class 12 Mathematics

# How to Score 90%+ in CBSE Class 12 Mathematics The CBSE Class 12 Mathematics exam is a monumental milestone. Unlike some curricula where creative problem solving is key, CBSE heavily rewards algorithmic precision, speed, and thorough familiarity with the NCERT textbook. ## 1. NCERT is the Bible It cannot be overstated: the NCERT textbook is your foundation. Before you touch R.D. Sharma or any reference books, you must be able to comfortably solve every single example and exercise question in the NCERT book. ## 2. Weightage Matters Be strategic. Calculus (Continuity, Differentiability, Integrals, and Differential Equations) carries a massive 35-mark weightage. Focus your energy disproportionately here. Vectors and 3D Geometry also offer high return-on-investment for the study time required. ## 3. Maintain an Error Log When you make a mistake, don't just erase it. Maintain a dedicated notebook logging the questions you got wrong and the underlying conceptual gap that caused the error. Review this log before every mock exam. ## 4. Presentation and Time Management In the boards, proper presentation is critical. State formulas used, delineate steps clearly, and box final answers. During practice, simulate the 3-hour limit strictly to train your time management muscles. ## The PerTuto Approach to CBSE Our specialized CBSE tutors have guided hundreds of students to the 90%+ percentile. We emphasize rigorous mock-testing and personalized feedback loops to guarantee results.
