The first is mathematics: Chen Wendeng and Li Yongle have training institutions, Wendeng is run by Chen Wendeng himself, and mathematics is OK. English: A good pilot or navigator (in fact, navigation and navigation are the same) can do it, but New Oriental can't. Politics: China's four great masters: Zhang Junfang, Chen,,. Navigation has the first three teachers. Ren Rufen has its own training institutions, but her own strength is limited after all.

Secondly, I want to make it clear that it is best to apply for three courses in a training institution. Because if you report separately, there will definitely be a time conflict. Most training institutions have classes on weekends and summer vacations. But if you sign up for one, the three times must be staggered. It won't be arranged at once. But if you report it three times, the time will definitely conflict. It is possible for three schools to start classes at the same time. You have to weigh this yourself.
