But if the score is high enough to be assigned to the best class, you can feel that there are still some professional teachers in your university (but generally those legendary figures will not come to teach undergraduate courses).
If you are not assigned to the best class, there is a gap between the teachers who come to teach and the teachers in the best class.
However, the overall learning atmosphere in the department is quite good, and most of the students are diligent and enterprising. There are many teachers whose spirits are quite inspiring.
If you do well in the exam and keep high marks, the school or institute you are sent to will be very good.
