Grasp the classroom: science attention is an ordinary study, not suitable for surprise review.
Think hard and ask more questions: you should not only "know what" but also "know why" the laws and theorems given by teachers.
Finish the homework assigned by the teacher with high quality: that is, improve the accuracy and speed.
5. Correct in time: Correct problems in time, and don't pile up problems.
6. Discuss with classmates or teachers.
7. Use modern tools to improve your interest in mathematics: People often say that interest is a person's best teacher.
8. Make mathematics close to life.
