How to prepare for 12th board examination.
Well !!! if your focus is to score above 90% in 12th board examination then focus should be on NCERT books and any one more text book.
In subject like Mathematics, you need to solve each and every exercise of NCERT book conceptually and thoroughly . Solving the book just once is not enough . You need to solve it multiple times. When you solve a particular question once you just learn how to solve. But what is required in Mathematics to be an expert. When you solve the same question again then you able to realize the depth of question. You may also try to solve the same question with different method.
Even greatest mathematician do the same things.
This is the golden rule to be good at mathematics.
When you go to write your board examination then you realize how good it was the solve the entire book again and again.
Other important books for 12th board examination are Mathematics by R D Sharma and R S Aggarwal (Good for CBSE Board) and K C Sinha (Good for Bihar Board). Mathematics for JEE Mains by Arihant publication is also good. All these books have lots of questions for practice. These books do have all questions from NCERT book. Question may come in your mind then why to solve NCERT book than?
Answer to this question is, NCERT have less number of repetitive questions to solve. So you can give more time to each questions.
