The so-called plan is what you can do after class, such as taking a break on Monday 12:30- 1:00; 13: 00- 13: 40 to do your homework; Stay for more than ten minutes after class in the evening to read books, wait for others to finish eating, then take a walk, and then prepare for evening self-study; Of course, you can be specific about what to do in the first class of evening self-study, what books to read, set the time and so on, but you should pay attention to rest and combine work with rest. Arrange one or two days every half month to review what you have learned before. Be sure to write down the date and when is the best time. I wish you success.
