JEE tips

Revise Fundamentals of thermodynamics: System and surroundings, extensive and intensive properties, state functions, entropy, types of processes with a one-page formula sheet before attempting mixed tests
After each practice set, log mistakes specific to Fundamentals of thermodynamics: System and surroundings, extensive and intensive properties, state functions, entropy, types of processes and reattempt after 48 hours
Revise The first law of thermodynamics: Concept of work, heat, internal energy and enthalpy, heat capacity, molar heat capacity with a one-page formula sheet before attempting mixed tests
After each practice set, log mistakes specific to The first law of thermodynamics: Concept of work, heat, internal energy and enthalpy, heat capacity, molar heat capacity and reattempt after 48 hours

Common trap

Students often rush Fundamentals of thermodynamics: System and surroundings, extensive and intensive properties, state functions, entropy, types of processes questions without checking units, sign conventions, or boundary conditions — always verify assumptions before calculating.
