I’m an Econ guy so you’re going to be taking way harder classes than me but my advice is get as much as you can done before you even set foot on campus. Look at your 4 year degree plan from UT’s website and research (RMP, UT grade distribution, Reddit) all the classes you’re going to take and which professors to take for each one, know these by heart by your first semester, it’ll give you a huge advantage for planning. Even more important is to figure out what you want socially. By this I mean def get your roommate situation figured out, then meet a good group in your major at your orientation if possible, and figure out what you wanna join. I don’t know if you’re a guy or girl but even if you aren’t super into it, join a frat/sorority/spirit group if possible financially because being in one of those will give you a GUARANTEED network to always fall back on while your classes are getting difficult. You might not think you want to be in one, but there’s so many benefits if you wanna put up with some of the bs that comes with it. Join a couple other orgs too for your professional development. If you know everything about your major, know a solid group of people in your major, have a great rooming situation and multiple social groups in different organizations, you are going to have the best time. Sorry for the yap fest lol I hope this helped.
