How can I put it? There is nothing good about it. Study independently. If you love learning, you can certainly learn something, and the school fees are high. Teachers like rich students, such as degrees. If you have money to give something to the teacher, the teacher will take care of you. I have many classmates. They never attend classes and work in other places, but many others have graduated. Any diploma or degree certificate can be hacked.

There is also a book that only focuses on a few points. A book similar to internal medicine and surgery, good at 1/3, and unsystematic in learning. If students have no initiative, don't go. If they want a diploma, it's all the same.
