Frequently Asked Questions

Which Physics formulas are most important for JEE?

Modern Physics, Electrostatics, Electromagnetism, and Rotational Motion appear in 9–10 out of every 10 JEE papers. These chapters are non-negotiable. Within each chapter, focus on formulas that have been used in PYQs in the last 5 years.

Should I memorise all formulas or derive them?

Memorise the key result AND understand the 1–2 step derivation path. JEE often tests boundary conditions and exceptions that only make sense if you understand the derivation. Pure memorisation fails on modified/combined formula questions.
