Not everyone can choose Class A, and exams are required at the beginning of school. Class A is not only more difficult, but also has more class hours than Class B, which is more difficult. If you want to take the postgraduate entrance examination in the future, it is still valuable to study calculus at this difficulty.

Class B is much easier and the exam is relatively easy. It's good to get a high score.

I studied Class A for one semester, and I changed to Class B in the second semester. Fortunately, I changed it. . Oh, the second semester exam in our class was almost wiped out. . At that time, we were still great monotheists of Meng Dawen, which was a terrible thing. Those who pass are only 60 points, and many people directly retake B!

I don't know the difficulty now. I suggest asking the children in grade 1 1. It's up to you.
