Limited Space I’m RT Program

I’m currently starting my prerequisites for my community colleges RT AS program. But the program at this school has 1/5 chance of being accepted. I’m just worried I will go through all of this and then not be accepted next year. Did anyone else deal with selective programs? Is there anything I can do besides get good grades? I plan on asking my advisor when I can speak with them but it’s giving me anxiety so I though might as well ask.
