Frequently asked questions

What makes a Union, intersection and complement of sets and their algebraic properties question "important" for JEE?

Important questions test core concepts that appear frequently across JEE Main and Advanced papers — definitions, standard formulas, and classic problem types.

Which subtopics in Sets, Relations and Functions are high-weightage?

Key areas include Union, intersection and complement of sets and their algebraic properties. Prioritise these before moving to edge cases.

How many important questions should I revise?

Revise 30–50 important MCQs per unit in the last month before JEE. Focus on questions you got wrong at least once.

Can I practise only important questions on Goodmarks?
