Look at the difficulty of the problem every year. If it is 540, the chosen school should be able to pass the exam, but it may not be guaranteed if you pass the exam. Relationships and money should solve the problem of insufficient scores. The arts and sciences are all good, but the school pays more attention to science. Generally speaking, there are more liberal arts students than science students in Tsinghua Peking University, but the enrollment rate of liberal arts students is not as high as that of science students. The school is really not strict. There are too many self-study classes. If you don't want to study here, you are very free. If you want to study, you are super tired. Of course, most of them are children who love to learn.
