Preparation Strategy

Based on the analysis of chapterwise weightage of maths in JEE Mains, here is a preparation strategy to ace the upcoming session:

Focus on high-weightage chapters first: Give most time to Calculus, Algebra, Coordinate Geometry, and Vectors & 3D Geometry - these cover 70-80% of questions.
Build strong basics and practice daily: Start with NCERT concepts, then solve 100–150 problems every day (mix easy, medium, and tough) to improve speed and accuracy.
Revise formulas: Keep a notebook handy for key formulas, shortcuts, and common mistakes so revising them becomes second nature.
Solve previous years' questions and take mocks: Practice lasts 10–15 years' JEE Main Maths PYQs and full timed mock tests weekly - analyze errors immediately to fix weak areas and manage time better.
5. Manage time and stay consistent: In the exam, attempt easy questions first. Study 2–3 hours daily on Maths and avoid new topics in the last month.
