How to become a good student

There are many ways to become a good student. For me , I'm not a good student in all subject but I'm good at math subject. Many people said that Math is too difficult for them to study. But in fact, If u try to do a lot of Math exercises, It would be easy for you. You don't need to find new exercises to do, Exercises that you have learned from school. When you get back home, you must try to do them again and again, again and again everyday. You must try to understand their exercises. Just remember the ways to study Math is trying to understand not trying to remember all things. If u understood, u would know how to do exercises without looking to the book. When u do like this only one month, Your math will improve
