Hi, are you talking about choosing a major or what courses to take? If you're choosing courses, you can probably take all of them, or some this year and some next year. If you're choosing your major, if you're about to be a freshman, you can be "undecided." If you're not a freshman, then you'd probably want to talk to a councelor/advisor to choose. I'm an incoming freshman (sociology and statistics) so I can't tell you how any classes are. Good luck though!
