1) Be confident and believe that you can learn well.
2) Listen carefully in class and follow the teacher's ideas. Think positively and speak positively.
3) The most important thing is to ask yourself why on the basis of understanding what the teacher said. That is the process of self-enlightenment. Reverse what the teacher said. The ideas and skills contained in it. Really turn what the teacher said into your own. After a long time, your problem-solving ability will improve.
4) Take notes in time. Summarize the teacher's way of thinking, his own laws and some inspirations in the process of doing the problem by himself in time.
5) Be good at asking questions. Don't be afraid to make mistakes. Students' learning ability and psychological quality are improved in the constant alternation of right and wrong.
