There are other textbooks apart from the NCERT book that you might be familiar with. You must grab them immediately as they will expand your knowledge and give you a different perspective through their styles of explanation of the same topics. Some of the important ones are books by H.C Verma and S.L Arora for Physics, R.D.Sharma book for Mathematics, book by OP Tandon for physical and inorganic chemistry and NCERT for science is very effective.

4. Is there any negative marking in NSEJS?

Yes, the set A of the NSEJS exam has negative marking.

5. Can Class 9 students give the NSEJS exam?

Yes, the eligibility criteria of NSEJS states that students in high school who are in the 10th or lower classes and have not yet completed their 10th board examination with passing marks before November 2022 can apply for NSEJS 2022 exam.
