I can tell you: the essence of science comes first. As a repeat student at home, I have also heard a lot about basic online schools. Who says science is better than essence in other schools? There is no evidence. At least I've heard most of them. According to my experience. The study and thinking of science can reach the essential level in Wu Haibo, and chemistry is superior. Most teachers are too young, and their teaching level is ................................................................................................................................................................... Just because you hold the title of competition doesn't mean you are first-class. As for the simple learning network, the teachers are very good, but the course capacity is small, and of course the price is very cheap. Science suggests only listening to physics and mathematics. I dare not comment on liberal arts. Who's so amazing? Have you heard all the best arts and sciences? Say science is not good. There is no basis. I doubt whether they have heard of it. I have been a student of elite online schools for a long time. I first learned about it on the BBK learning machine, and then I listened to it on the computer. I feel that science may make Yuan Tengfei, a liberal arts student, lose the limelight, but I really didn't say anything. I used to think there were fewer chemistry classes (no school, self-study), but recently I added teacher Gao Donghui, so happy.
