Whether the remedial class is good or not depends mainly on whether the knowledge framework is established, whether the students have learned something, whether they have a sense of responsibility, etc., rather than the so-called betting questions. Don't believe the betting questions. It's hard to guess the question now. Imagine that the old professors in the test proposition center do this every year. How can they easily let you guess? Therefore, it is the key to lay a good foundation, and change with the same.
There are spring basic classes in spring, so you don't need to apply.

The finishing touch class is to say the key points at the end, and then add flowers to the well according to the topic. It is good to bet right. Now it is rare to bet right.
If the foundation is not very good, you can start with a basic class in spring, or an intensive class with a better foundation will do.
