1, the advantage is that the learning atmosphere is strong, and Bai Fei's excellent training is conducted in the form of class, which can quickly integrate into the classroom atmosphere and help improve the learning effect.
2. The disadvantage is that it is not flexible enough. Because Bofei Peiyou is a class, class is a fixed time and place, and it will not change because of one person. If students can't attend classes for their own reasons, they can only miss classes, and it will be very troublesome to make up lessons in the future.
