Technical secondary school is indeed useless, but you can advance to junior college after graduating from technical secondary school, and then transfer from junior college to undergraduate. Technical secondary school is just like high school. It is just a transition, not the end. But it still depends on your personal efforts. In the general environment, your own efforts are very important. Moreover, it depends on how a person will be in the future. Academic qualifications are no longer the most important factor, but the importance of academic qualifications cannot be ignored. Sexuality and academic qualifications are a label for a person and also a stepping stone. I hope you will adopt them, thank you.
