Lele classroom. Lele class is taught by super-class people's teachers and senior people's teachers, and the teaching level is even better. The enrollment rate of students in Lele class is 96% every year. It only takes a few minutes to learn a knowledge point, so as to avoid students from paying attention to online classes for a long time. However, the course of onion mathematics takes a long time and students have no patience to finish it, so Lele class is better.
