You can't go to an undergraduate course if your score doesn't reach the undergraduate score line. Even if you find a relationship, it is basically impossible. At present, the state has strict control over the admission of college students, so even if you go to college, there is no information about your student status, because colleges and universities should establish their student status on the basis of voluntary admission, otherwise it will be entered into the system now, and you will not be able to enter the system at all.

You can have two choices now, either go to such a better institution or repeat one year and get a good undergraduate course. As long as you work hard, the improvement in one year is still great. I suggest repeating it, because enterprises in society now value the first degree of talents most. In other words, if you want to go to junior college and get into a good school for postgraduate entrance examination, it is actually of little significance, because enterprises value your undergraduate stage more. As the saying goes, first-class undergraduate, second-rate graduate student, third-rate doctor.
