During school, the final exam score must be above 80 points. You should take the exam with a purpose, not just pass it, because it will affect the schools that apply to go abroad. However, the schools that have been upgraded from junior college to undergraduate college are generally not key universities, so you have little advantage when applying for postgraduate study abroad, so be prepared psychologically.
If you don't pass the college entrance examination, you can work for two years first, and with two years of work experience, you can still apply for studying abroad.
It's too early for you to think about it now. Let's do it step by step. There are five years left. You might as well just give up junior college and go abroad to study at a university. This is the choice of many college entrance examination students. One of my classmates is not too late. However, when your classmate is a sophomore, you will be a freshman, because you have to learn languages and preparatory courses first, which is good.
For the sake of my hard work, if you are satisfied, please give me the score. Very tired
