JEE Main Formula Sheet — Important Formulas (Physics, Chemistry, Maths)
It’s the last fortnight before the exam. You’ve done the syllabus, you’ve solved the papers — and yet, sitting down to revise, your brain suddenly blanks on whether the first-order rate constant has a 2.303 in it or not. That panic is normal, and it’s exactly what a formula sheet is for: not to learn from, but to keep the high-yield formulas one glance away when you’re revising or stuck mid-problem.
Instead of squeezing a handful of formulas into this page, we’ve put the whole thing online — free, chapter by chapter, for Physics, Chemistry and Maths. No login, no PDF download, no email wall. Below is how to actually use a formula sheet, and where to find the complete set.
First — how to actually use it
Here’s the mistake almost everyone makes: they read the sheet and feel productive. Reading formulas is passive and forgettable. Instead, blurt — close the sheet, write every formula for a chapter from memory, then check. The gaps you find are your real revision list. Do that a few times per chapter and the sheet stops being a crutch and becomes a five-minute confidence check before the exam.
The complete JEE Main formula sheets — free
Rather than a cramped 20-formula table, we maintain a proper chapter-wise formula sheet for the entire JEE Main syllabus — every chapter in Physics, Chemistry and Maths as its own clean reference sheet. Each one carries the key formulas, definitions and theorems for that chapter, plus the common examiner traps, quick shortcuts and a few worked examples — the high-yield essentials, nothing padded.

A formula sheet is most powerful when you weight it by what the exam actually asks. The Electrostatics, Current Electricity and Optics formulas in Physics, or Coordinate Geometry and Calculus in Maths, appear far more often than the rare ones — so spend your revision minutes there first. See exactly which chapters carry the marks with our chapter weightage tool, and fold the sheets into a structured final month with the 30-day revision plan.
One last thing: a formula you can recall but can’t apply under time pressure is only half-learned. After you blurt a chapter’s formulas, immediately solve a few previous-year questions on it — that’s what turns a memorised sheet into marks on exam day.

How should I use a formula sheet for JEE Main?+
Don’t just read it — “blurt” it. Close the sheet, write every formula for a chapter from memory, then check against it. The gaps you find are your real revision list. Used this way, a formula sheet becomes a fast, high-yield revision tool rather than passive reading.
Which formulas are most important for JEE Main?+
Weight your revision by exam frequency: in Physics, Electrostatics, Current Electricity and Optics; in Maths, Coordinate Geometry and Calculus; in Chemistry, mole concept, thermodynamics, kinetics and electrochemistry relations. Prioritise the high-weightage chapters first.
Should I make my own formula sheet?+
Making your own is one of the best active-revision exercises — the act of writing and organising formulas cements them. Use a ready sheet as a checklist to make sure you haven’t missed anything, then rebuild it in your own words.
Do I need to memorise derivations for JEE Main?+
JEE Main is objective, so full derivations are rarely tested directly. Focus on knowing the final formulas cold and being able to apply them quickly — but understanding where a formula comes from still helps you use it correctly and avoid traps.
