It should be said that this student has high learning efficiency and strong self-study ability. Skipping classes often thinks that you don't listen to this lesson, but you think that you have mastered the main points of this lesson.

The same is true for playing mobile phones in class. He may only listen to the main part, or he may listen while playing. Maybe he has mastered it, and it doesn't matter whether he listens or not.

Actually, it's no big deal not to do homework. I always thought that children would learn better if they did less homework. Too much homework consumes energy and time.

You can get 70 points at the end of the math class in senior two, with a full score of 100, which is still acceptable. Some students work hard, which may be the result.

Of course, if he works harder, he should be able to get better grades.
