Let me make two points. First, I think my efforts and attitude are more important, because if you don't learn at all, any fairy panacea is useless. So don't worry about anything else, first of all, your learning attitude should be correct. Second, you can save a lot of time if you learn from a teacher who is familiar with the outline, direction and content. For example, the teacher said that you should study hard from page 33-127, so you don't have to look at so many things that you haven't passed the exam, so you will concentrate a lot of time and spend your effective time reviewing where you can get more points, okay? Third, modest education is still very good. Our township doctors review exams according to their requirements.
