Only by laying a good foundation can we learn deeper knowledge. There are still more than 1 year before the third grade, which is enough for you to catch up on math. Don't have psychological pressure. Working hard on basic knowledge points may not have a great effect in a short time, but you must stick to it. In this way, although the workload may be greater than that of other students, you can study in a down-to-earth manner, and only when you have a good foundation can you learn well. Don't aim too high, you must master the foundation and then focus on other places. To learn the basics well, it is necessary to practice the intermediate questions diligently, so as to understand the knowledge points in a deeper level and deepen the impression.

A total score of more than 60 points means that knowledge is lacking and incomplete. You must listen carefully in class. The teacher's role is not to give you knowledge, but to save you time.

Maritime tactics. The important thing is not to do the problem, but to find your own knowledge points in the process of doing the problem and make up your own shortcomings in a targeted manner. If necessary, you can extract the wrong questions into your notebook for easy reading.

Basic and intermediate questions are very important. In view of your situation, don't work hard on the difficult problem for the time being.
