school school school

I have realized that trying hard in highschool is completely different than trying hard in college. I don't really know if I am doing really well in any of my classes and I feel like I really need to step up my game but maybe its too late. The semester is almost over but I guess there isn't ever a too late. I am soooo stressed out about it and don't know what to do. I'm sure lots of other freshman feel the same stress I do but it seems like I am the only one who is freaking out about this. Maybe someone of you freshman can relate a little bit who knows....back to studying haha.
