Frequently asked questions
What makes a Classification, isomerism, IUPAC nomenclature, general methods of preparation, properties and reactions 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 Hydrocarbons are high-weightage?
Key areas include Classification, isomerism, IUPAC nomenclature, general methods of preparation, properties and reactions. 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.
