How about Shangkong education? How is the teacher's teaching level?

I don't know. There will definitely be more right and wrong after the organization grows bigger. In contrast, many small organizations are not qualified. Do you think it is reliable to have no teacher qualification certificate? At the training institution, all teachers have renewal fees as assessment indicators. Do you find it interesting not to give you two or even three classes? Small institutions tend to pay more attention to the relationship with students. To please students, it takes a lot of time to gossip in class. Naturally, students will not say that teachers are not good, and many small institutions are not cheap. Parents should check whether they are qualified when they register for the training class. At least the elite teaching and research group is discussing it. Many small training institutions buy or download lesson plans directly from the Internet. Let's see if they are qualified. Training courses cannot be built above the third floor, and many institutions are built in office buildings.

As for grades, training courses generally adopt the strategy of "asking questions in the sea" and "ahead of time", so that you can do the questions several times in advance, which is why many people usually do well in the exam, but the college entrance examination is a mess.
