Learn physics the way it actually works.
Clear notes, mind maps you can revise in ten minutes, animated concepts and NEET-pattern tests, all written by a classroom physics teacher. Every chapter, from first idea to exam answer.
Pick your class. Every chapter is ready.
Everything you need, in one tidy place.
Each format does one job well: notes to understand, maps to revise, questions to practise, tests to prove it.
Chapter notes
NCERT-aligned notes with derivations, solved examples and the exact lines examiners look for. Download any chapter as a PDF.
Mind maps
A whole chapter on one page, so revision the night before takes ten minutes, not two hours. Printable and colour-coded.
Question bank
MCQs, assertion–reason and numericals, sorted by level, each with a full worked solution.
Sample papers
Board-pattern papers with marking schemes and model answers that show how to write for full marks.
Test series
Timed NEET and JEE pattern tests with an All-India rank and a chapter-wise report of where marks slipped.
Which book, for which student
Plain verdicts on the books students actually use: who each one suits, which chapters to skip, and how to pair it with NCERT. Links go to the best current price.
Launch a ball. Watch the formula come alive.
Change the speed and the angle. The range, height and flight time update as you move, the same numbers you would get from the equations in your notes.
Try this: set θ to 30°, note the range, then try 60°. Same range. That is why the textbook says complementary angles give equal range.
One loop, repeated for every chapter.
Students who follow these five steps in order stop memorising and start solving.
- STEP 1Learn
Read the chapter notes and solved examples.
- STEP 2Visualise
Watch the animation until the idea clicks.
- STEP 3Connect
Revise from the one-page mind map.
- STEP 4Practise
Solve questions, easy to exam level.
- STEP 5Test
Take the timed test and fix every mistake.
Know your rank before the real exam does.
Weekly chapter tests and full-length mocks in the exact NTA pattern. Every question comes with a written solution, and the tough ones with a video.

SeriesThirty seconds. One concept. Try it.
A ball is thrown straight up at 20 m/s. At the highest point of its flight, what are its velocity and acceleration? (Take g = 10 m/s².)
Pick an answer to see the explanation.
The full solution, and the mistake most students make on this question, appear here once you answer.
Velocity is zero, gravity is not.
At the top the ball stops for an instant, so v = 0. But gravity never switches off. The acceleration stays g = 10 m/s², pointing down, at every point of the flight.
a = −g = 10 m/s² downward, throughout
Common mistake: “velocity is zero, so acceleration must be zero too”. If acceleration were zero, the ball would stay at the top forever.
The right book saves you a month.
Concepts of Physics
Builds understanding from first principles. Best read alongside NCERT, chapter by chapter.
NCERT Exemplar
Short, tricky questions straight from the NCERT text. Many NEET questions follow the same style.
Problems in General Physics
Hard problems for students aiming at JEE Advanced. Skip it if NEET is your only target.
“Physics is not a list of formulas. It is a handful of ideas that explain everything around you. My job is to help you see them.”
I have taught Class 11 and 12 physics for twelve years, in classrooms and online. PhysicsDNA is everything I wish my students had in one place: the notes I write on the board, the diagrams I draw, and the questions that catch people out.
