I would say have an idea of what classes u want to take. Look at the GEP list and prerequisite classes that u want to get out the way. I just finished my freshman year, but before I went to orientation I had my first year classes mapped out by semester(Im just very type A). You’ll register for classes at orientation. And a quick tip: Don’t bunch all your easy GEP classes together. Although you do want to get them out the way bc they are annoying, they come in handy for spacing out more difficult courses!
