Frequently asked questions

What makes a Logic gates (OR, AND, NOT, NAND and NOR) 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 Electronic Devices are high-weightage?

Key areas include Logic gates (OR, AND, NOT, NAND and NOR). 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?

Pro users can filter by unit and subtopic to target high-yield areas. Free users can attempt sample questions on this page.
