Is learning NCERT sufficient for JEE concepts?
So, one thing is clear. Additional subjects not listed in the ncert need not be studied. Don’t expect direct questions from ncert for the weight of ncert questions. The JEE standard is not as simple as asking directly. There are always new questions on paper, but none actually taken from the NCERT curriculum. As for chemistry, if you’re lucky, you might get a direct question from the inorganic part, and if you ask about the physical part, you’ll get nothing direct from the physical part. If you got it, you may be too lucky. We are talking about physics and mathematics. In physics, questions may arise from further practice, just as there were direct questions before. Don’t even think of asking simple math questions from ncert directly . NCERT is the basis for preparation, so you should prioritize it, but you should look at other books to better understand the concepts and solve different types of problems. So please complete the ncert first, learn all the concepts in it and treat the other books as references. NCERT is the most important for all the three subjects, particularly for Chemistry. As you aspire to self-study, questions are bound to arise. There must be good video lectures.
Study physics and chemistry especially well, as most of the questions are on topics mentioned in the book. But don’t expect direct questions.
