I have been a representative of all classes, but I am an English class representative. Hurry up and make up for the poor foundation. Mathematics is closely related, which is different from physics. If you don't learn well now, it will be difficult to make up for it later. Knowledge is accumulated, and I believe the difficulties are similar. So now is the time to lay a good foundation and review what I didn't know before. So now that we know our own situation, we must work harder. If you think there is something wrong with your method, I suggest you hire a tutor. Because I have always been a tutor, I know a little about the situation. This is just a suggestion. Just try it.
