Hmm? Since it is a handout, the teacher will naturally explain it. But usually everyone does it first and then listens, because what they listen to is the ideas and methods to solve the problem, not the problem itself ... If you can't do it at all ... I'm afraid you have to stop the remedial class first and agree to the textbook first! ! !

You must understand that remedial classes are only for counseling, and ultimately it depends on your own basic situation.

You have to have a foundation to go to the remedial class. You want to spend four hours a morning discussing a chapter! ! ! If you don't have a foundation, you can't learn solid at all!

You can find the answer online, there should be some, or you can buy it in Wenhai. But you pay money to attend classes, not to buy questions. Wait for the teacher to explain. If he doesn't say anything, Wenhai will give you the answer.
