Honestly. As another college student, if you're one of those who can work under pressure and get the job done without getting distracted during the way, I'm pretty sure you'll be fine. Plus making sure you talk to you teachers is a BIG part of college because if you're having any problems, YOU HAVE to tell them right away. I did the exact opposite in my first year of college going in thinking this was going to be ez life and boy was I in for a surprise.
