For transfer students, it is several times more difficult to enter the school than during the Middle School Entrance Exam. There are two ways to do it, 1. Rely on parents' capital and connections. 2. Rely on their own academic achievements and talents.
Academic grades can be checked, while talents don't require any performances, just show their certificates.
The school doesn't have the time to watch students showcase their talents because there are already hundreds of transfer students lined up to attend.
The Admissions Office is swamped, having to deal with this kind of situation every summer vacation. However, there is no other way. In addition to recruiting students during the Middle School Entrance Exam, digging talent from other schools and selecting excellent transfer students from all over the country is also a way to refine the student team.
Of course, pushing people in with background connections is also a downside.
