Yeah definitely do. Besides finding your classes, is there anything else you're worried about? And as for your classes, look up a campus map and find the buildings. Once you've found them, getting to the classroom itself is pretty easy. Sometimes it'll even work on Google Maps so you can see where they are and how long it takes to walk to each one.
@ PoeticMess. I might take you up on that because I'm so nervous. I start Monday and my stomach is in knots. Thanks for the comment it helped a little! :)
It's normal to be worried and anxious! Starting college is a big deal! But it'll be great. You'll find your classes and even if you can't right away, professors understand that it's unfamiliar territory. As for public speaking, I doubt you have to worry about that for awhile. The first week is syllabi week. If there's one thing that's important in college, it's your syllabi. They're all-knowing!
If you want to talk about it, I'm here! I go back the 19th for my third year which I'm super excited about. Your classes look interesting, which is the most important part!
It should be fine! :)
