Let me talk about the topic of mathematics. Synthesis of other subjects: I think if your basic knowledge is ok, that is to say, if your exams are all above 100 (150 full mark), then do more questions, read more reference books and be good at summing up yourself. If it is at 100, it means that your foundation is not enough, and carelessness is not an excuse, but a weak foundation. In the second case, please read more textbooks and do the examples and exercises in the textbooks.

The second question:

You must have a special notebook to take notes, and it is recommended to use a loose-leaf notebook to supplement and organize your knowledge at any time.

The third question:

When I was in senior three, I had a weekly plan. The main task during this period is to follow up the teacher's progress and review carefully. Do what you can do today! Staying up late is not so terrible. Senior three is only one year. Always tell yourself that you still have a dream and you will stick to it.

Have a good review.
