If you just want a college diploma, you can choose the adult college entrance examination or the self-study exam. It is relatively easy and fast to get into the exam, and you don't need to attend classes, but the gold content is not high, so it is more difficult to take the self-study exam.
If you want to go to a unified university and feel the campus environment, you have to review well and prepare for the college entrance examination. There are many kinds of universities, undergraduate, junior college and independent college. Good universities are also divided into 2 1 1 and 985. Although many other schools are not the focus, they are very professional, so the admission of this major will require high scores.
Personally, I think it is too difficult to go to a good university last year! But you can't rule out the possibility of miracles, if you have talent and self-control. It is not difficult to apply for a reasonable exam if you want to go to an ordinary college. You'd better collect information about the university you want to go to first, and you need your own efforts.
I hope I can help you, come on!
