Summer college class..

I’m currently in high school right now, and my school allows us to take a class (such as history) to get ahead. My high school partners up with the nearby community college so I’m getting college credit when I finish this class (transcript). My main concern is that I’m not doing too well, and I don’t want to order my transcript if I don’t do well. But, when I actually do apply for college, do I have to order this transcript? Will the college I apply for find out (or find me dishonest)? Thanks!
