Judging from the source of the three books, the proportion of students who are lazy and playful is relatively large. The school takes making money as its first goal, so the school atmosphere is really not so good. There won't be many students with real talent and learning. Many students just "mixed" for four years and "mixed" a diploma.

Of course, the key is to look at the students themselves.

Suggestion: See if there is a suitable vocational college or choose a good one.
