Well...Guest, you can be sure NO ONE has any clue what's going on. Which makes it easier to talk to and get to know people. Because you can rage with anybody about how confusing that shit is. At least that's my experience.
Try not to spend much time as undecided, knowing what your end goal will make it much easier to manage your time and plan accordingly for what courses you need to take when. Also know that it’s nothing like high school. Good luck!
Try to learn and be a good student, but also to enjoy your time there. You'll possibly learn quite a bit about yourself. It's a short period of time but a precious one, make it count. :)
And don't worry, everyone is as lost as you are. You'll figure It out

That goes for school and social life
