HAHAHAHA LOL...... don't worry about it, you'll be fine... Starting college for me was just going back to school. It's nothin but going back to school. But in college you get to meet different types of people, I think it'll be a great experience and you'll enjoy it.
About failing college?... wow you really have serious thoughts in your head..haha.... j/k.... It all depends on you, if you stick to the studying and try your best, and try hard... then you have nothing to worry about it. Of course I can tell you that, for some classes, you don't need to study at all and still get an A, and as for some other courses, you might study really hard and get a C. It kinda depends on your major also...I don't think you much to worry about. Take it easy, learn as you go... Gooooood Luck to you....
