Since the grades are poor, we must find the reasons. Only by finding the reason can we catch up with the result.

The main reasons for poor grades are the following three reasons.

One is the poor foundation. You are a senior, because you didn't learn well in your junior year, you will not be able to accept new knowledge and your learning effect will be affected.

Second, the learning attitude is not correct. For example, you don't listen carefully in class. I didn't get ready before class. Do not finish your homework carefully after class.

Third, there are problems with learning methods and habits. For example, you don't want to recite what you should. Such as English words, historical knowledge and so on. You don't want to write what you should practice consolidating. For example, you don't practice math well.

In short, you should sum up yourself and find out the problems, and then you can improve your grades better. I wish you study hard and make progress every day.
