As a college student, I haven't touched math for four years, but I almost forgot it. I remember that high school and math teachers can get more than 1 10 in the college entrance examination every day. It shouldn't be difficult to do more questions, and everyone's goals are not perfect. Try to take as many exams as possible.
If I speak English, I have to say a few more words (the college entrance examination is also an English-related major). The foundation of English is really important. The reason why I got good grades in English at the beginning was that I met a teacher who brushed the questions for three years, so junior high school was an English major. Later, you will find that English (if you take the exam) is actually so many things. Just do more problems and accumulate more experience.
I don't have much say in some computer exams, because my second grade also passed half a month in advance ... in fact, it's just memorizing knowledge points. Pick a software on your mobile phone that you can practice at will, and answer it when you think of it. The operation problem is on the computer. There is no other way. (I really can't see it by watching the video, but it may vary from person to person. Try them all. )
I have no say in ideological and political education. As the best science student in Chinese, I feel that learning something is messy. Learn more.
Anyway, as long as you pay attention to the correct review methods and improve your learning efficiency, you will find that upgrading from junior college to undergraduate course is not an insurmountable hurdle. If you have a chance to try, you must try. I wish you success ~
