However, what do you think of their large and small class teaching? I feel the same way. It depends on whether you are willing to learn. If you don't learn, n is useless to one. Willing to learn, it is better to ask more teachers at school. . . . . . If you really want to apply, go to a class of 20 people for 50 hours. The most useful ones are 1 to 1. Learning and thinking, in addition to one-on-one, should be divided into classes, generally small classes of 20-30 people. Don't talk about the big class, it's useless to go, the teacher can't control it at all ... Let's talk about the placement of the exam (elite class and ordinary class) first.
