You see how strong the relationship is, but it's only when you get to the university line that it's so easy to get into two books. If you don't really have the strength (or financial strength) at home, it's just bragging. Undergraduate schools are not so easy to open the back door. Usually you get enough grades, and then you can get a good major that you can't rely on ... and it depends on the place. Some provinces are easier to involve, while others are not so easy.
Of course, if you do well in the college entrance examination, you can also go to a good university, but only if you do well. Nothing is simpler than the college entrance examination.
Ps: I always think your friends are bragging. Two of them went to major without going to school. He is afraid that he will fail in the exam twice and eventually won't get a degree certificate, but he still wants to climb up bit by bit through hard work. . .
