B. Whether the content is comprehensive, it is best to have a study outline, and you can see at a glance whether it is a complete knowledge system;

C. Whether the content is professional or not does not mean that a famous teacher can definitely teach good students. The key is to be practical. The best content involves more case demonstrations and skills, so that you can learn step by step and strengthen your practical ability.
