Listen carefully in class at ordinary times, and pay more attention to learning than others after class. It is not difficult for you to understand all the knowledge points. It's difficult to take the exam casually, which means that your foundation is not solid and you haven't found a suitable learning method yet. It is also necessary to study mathematics for postgraduate entrance examination. See if you have worked hard on it. I don't know if you can ask the teacher if you can understand the topic, and if you don't ask, it will be very difficult and you won't fail the exam. So the basic skills at ordinary times are still the main ones.

No matter how difficult the problem is, some people can solve it, because they listen carefully in class and the same teacher is teaching. Why do some people do this? Because they are attentive, it is much more efficient to listen to the teacher attentively than to find a learning method after class. You can find the real questions of mathematics postgraduate entrance examination over the years, and you can answer them once. Anyway, the questions are the same. You can answer it yourself first. 20 19 it's still early for the postgraduate entrance examination. After you check your answers, if you make mistakes, you can find out where you have not learned solidly and which links you don't understand. If you don't understand, you should ask the teacher to understand the problem in time. The teacher said you did it for your own good. The more you are afraid, the more you pretend to understand.
