Review biology first, summarize and browse the main notes or knowledge handed down by the teacher, and remember the important contents. About 30 minutes is enough.

Then review mathematics, recall the key points of each chapter, look at the questions that will be done in the senior high school entrance examination and monthly examination, find out the reasons for the deduction, and find some to do it again. It will take about 40 minutes.

Finally, review geography like biology.

Then tidy up the stationery for tomorrow's exam and go to bed.

I wish you good grades in the exam.
