3. Do a set of wrong questions by yourself

(PS. These three points seem simple, and there are not many that can be done and adhered to. I didn't do it. . . Taking notes in class only focuses on the key points, and the teacher will speak quickly. Just remember the key steps. Do it again after class, and take the time to do it again for the wrong set of questions. Just do it. Come on, I hope it helps you. )
