Frequently asked questions

What is PiTheory Learning?

PiTheory Learning is a physics platform for NEET and JEE aspirants: a free NCERT chapter-wise question bank with step-by-step solutions, plus online classes with concept-based teaching, problem solving, doubt clearing and tests.

Are the solutions checked?

Every solution is checked by the PiTheory team, led by Sreeraj P (M.Sc Physics, 10+ years teaching JEE and NEET). If you spot a mistake, tap Report on the question: we recheck it and correct it.

Are these questions from previous years?

Many are previous year questions from NEET, JEE Main and JEE Advanced, marked with the exam and year. Others are original practice questions written for the same pattern.

Is it suitable for both NEET and JEE?

Yes. Each question is tagged NEET, JEE Main or JEE Advanced. Numerical value questions follow the JEE Main pattern.

Do you teach from the basics?

Yes. Every chapter starts from fundamentals, then moves to exam-level problems.

Are there separate batches for Class 11, Class 12 and repeaters?

Yes, for both NEET and JEE.

Is NCERT enough for NEET physics?

NCERT is essential, but high scores also need extra conceptual practice and numerical problem solving. The question bank follows NCERT chapters so you can do both together.

How many physics questions should I solve daily?

Regular daily practice matters more than long occasional sessions. Aim for 30 to 40 questions a day, including revision questions.

Do you teach students in the Gulf and abroad?

Yes. Flexible timings for students in the UAE, Qatar, Kuwait, Oman, Bahrain and Saudi Arabia, and also Singapore, Malaysia, the USA, UK, Canada and Australia.
