I think their online school courses are average, and I have seen some. However, I watched the videos of Dali Education and Luyou Education Online School and Hi Learning Network when I was admitted to Jianyi. I feel that the teacher inside is still very stylish and can grasp the key points. No matter which online school video you watch, you should study hard, mainly depending on your understanding ability.

Everyone does research after work, mainly relying on online school teachers to give lectures, and usually don't have much time to read books. Public classes, watching online classes and doing some real questions over the years are enough. In practice class, you should understand more and do more problems. Doing practical problems is the best way to combine the teacher's lecture video.

Online school is a complete process of realizing off-campus teaching through the internet; As long as you can surf the Internet, you can surf the Internet anytime and anywhere and choose your own learning content. Compared with face-to-face education, online education has broken through the time and space limitation of education to the greatest extent. It is a teaching activity that separates teachers from students, not organized face to face. It is a cross-school and cross-regional education system and teaching model.
