1. Keep a good attitude, don't be impetuous, and continue to do a certain amount of exercises every day to ensure the speed and accuracy of your own problems. If you can't meditate, then in the rest of the time, you will not only fail to make progress, but will probably regress, resulting in your unsatisfactory final exam results.

2. Analyze the wrong questions and find out why each set of papers can't get full marks. Is it a calculation error, or a loophole in the knowledge point, or you have no idea at all when you see the topic, and whether the wrong questions in each set of test papers are regular, return to the textbook in time to check for leaks and fill in the gaps.

3. Redo the questions in the wrong book. Since I made a mistake in the last question, it must be something wrong with my thinking or calculation. If I redo the wrong question, I can make up my own thinking hole.

4. Make the real questions of other papers into simulation questions. Teachers can refer to other kinds of papers to write questions. If you do the same type of questions in advance, it is equivalent to predicting the questions in advance in the examination room, so doing the questions has advantages. Moreover, as a simulation question, the real question is definitely closer to the postgraduate examination paper than other simulation questions.
