Integrals — JEE Questions, Notes & Weightage
Class 12 Calculus NEET weightage: Very High 159 questions
Covers integration techniques (substitution, by parts, partial fractions) and definite integral properties. Often considered the single highest-weightage chapter in all of JEE Maths — integration-technique questions appear in nearly every paper, sometimes more than once.

Frequently asked questions
Why does this chapter carry so much weight in JEE?
Integration combines algebraic manipulation, trigonometric identities, and several distinct techniques (substitution, by parts, partial fractions) into problems that can be made arbitrarily intricate — exactly the kind of multi-step difficulty JEE rewards.
Which integration technique is tested most?
Definite integrals using properties (especially the King's rule, ∫f(x)dx = ∫f(a+b−x)dx) and integration by parts are the most frequently repeated, highest-value techniques.
