Is NCERT enough for Class 12 Maths numerical questions?
Yes. For the class 12 Maths final exam, questions and solved examples of NCERT textbooks and examplars solutions are more than enough. But for other high-level competitive exams like JEE, Olympiads or BITSAT, students should also practice questions from other books and online materials. Frequent practice of mock tests can be helpful in both circumstances.
