There is another remedy:

1, listen attentively in class, don't play with your mobile phone, you may play until you can't stop, so listen to the teacher and remember more and prepare for the exam.

2, note-taking, university lectures are generally very fast, so you should take more notes, many students are still white after a semester, which is very bad, reading thousands of books, writing like a god.

3, do more questions, especially science majors, do more advanced math questions, understand all kinds of questions, and know them by heart, and you will be sure of the exam.

4. Usually grades are also very important. College exams are a combination of ordinary grades and periodic exams. Usually, your grades are determined according to how you answer questions in class, so you should be active in class.

5. Communicate with the teacher more and ask the teacher more questions. The teacher's impression of you is also very important, and you may give more impression points.
