As for how to review, I tell you, there is not much time, just look at the overall situation, read books every day, read all the books, upstairs is right, some things actually don't need to be memorized, just a little impression. The teacher said that the key point is to recite the pictures and important mountains the night before the exam, and pay close attention to the time of self-study classes (such as computer, sports, art, music, etc.). It would be better if there were a weekend. Learn geography one day and biology one day on weekends to ensure your success.
PS: mentality is the most important.
