I am also seeking knowledge. I am in the 25th science class. The supplementary school for knowledge is divided into ordinary liberal arts classes, key classes, top classes and art classes. The teachers there are quite good and they all come from other places with high salaries. There are many good teachers among them, and of course there are some bad ones, but they are generally good. However, the teachers there are generally bad-tempered and serious. In short, it is very hard during the year of seeking knowledge, and you mainly rely on self-study. If you really want to graduate high school, it is best to enter a key class or a top class. Of course, this also depends on your college entrance examination scores. According to my calculation, you can enter the top class with three books in my year.
The tuition fee for the first semester will be divided according to your high school score. For example, the first semester is 500, the second semester is 1,100, the third semester is 2,300, and the next is 3,900. If you don’t pass the exam, I won’t take it. It’s clear (according to my year), the second semester is a flat price of 2,900 (it seems to be, I don’t know exactly). Tuition is expensive, but there are bonuses for exams of all sizes. As long as you work hard, the money will be covered by the bonuses, and there will be more.
In short, work hard
