Biology is mainly reading books, remembering key knowledge points and experiments, and the phenomena of experiments must be clearly remembered. You can view the examples in the workbook. (examples of genetics must be carefully reviewed, which is generally necessary. )

If history is an open book, you only need to be familiar with textbooks and learn examples. If it is a closed book, then review the important knowledge points from the main to the secondary carpet. Key knowledge should be memorized, and non-key knowledge should be passed.
