High-weightage CBSE Class 12 Maths chapters, must-know formulas, and important question types for boards 2026 and JEE — with free chapter-wise practice and solutions.
Class 12 Maths is highly scoring if you target the heavy units and drill formulas.
Highest weightage: Calculus (Integrals, Application of Derivatives, Differential Equations) dominates the paper. Then Vectors & 3D Geometry, Probability, Matrices & Determinants, and Linear Programming.
Must-know: standard integrals, derivative rules, properties of definite integrals, vector/scalar products, and Bayes' theorem. Keep these on a formula sheet you revise daily.
Important question types: integration by parts/substitution, area under curves, optimisation (maxima-minima) word problems, and probability with Bayes.
Method: NCERT + exemplar, write full step-by-step solutions (process marks!), and solve a timed sample paper weekly.
