Frequently asked questions

What makes a Energy in S.H.M.: kinetic and potential energies 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 Oscillations and Waves are high-weightage?

Key areas include Energy in S.H.M.: kinetic and potential energies. 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?
