Mathematics is a scoring subject for CBSE class 12 students where you can even score 100 out of 100. However, it is possible only when you clearly understand the topics and practice them before the exam. Additionally, students must have a strong grip on the basics of this subject to solve the difficult questions. Since CBSE Class 12 Mathematics has more weightage, it is also important for engineering entrance exams like IIT JEE. You need to revise the important concepts and formulas regularly. It ensures their application for solving the most difficult questions in these exams.

We advise studying the NCERT 12 Mathematics textbook thoroughly before moving to any other study material. You should dedicate at least 1 hour daily from your study schedule to solving NCERT textbook problems. When preparing for IIT-JEE, try to solve as many questions from various study materials and take mock tests. Infinity Learn provides mock tests that will help you prepare for competitive exams like IIT-JEE. Keep a positive mindset and approach during preparation, and excel at this subject.
