Frequently asked questions

What makes a Thermodynamics 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 Thermodynamics are high-weightage?

Key areas include Thermal equilibrium and the concept of temperature, zeroth law of thermodynamics, Heat, work and internal energy, The first law of thermodynamics, isothermal and adiabatic processes, The second law of thermodynamics: reversible and irreversible processes. 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.
