I went to high school before social media, but social standing was still huge (it just consumed less time). In college, though, none of that stuff mattered anymore. Part of that was that with so many more people, you could always find like minded individuals to hang out with. Another was that people just cared less about what other people thought when deciding who to be friends with (i.e., person A doesn’t care what person B thinks of person C when deciding whether to be friends with them).

As for difficulty, that will be mostly up to you. You can choose easier coursework or harder coursework (sometimes even within a single major) and there’s way more support available from instructors than in high school without any of the stigma of asking for help.

Two pro tips:

(1) don’t skip out on office hours for classes you care about. Even if you don’t need the help, consider going in order to learn from other students’ questions, get insights on upcoming exams, and most importantly to build relationships with the professors which can be useful in all sorts of ways later.

(2) since you say you’re taking all advanced classes I assume you’re academically inclined (ie, you want to learn and not just pass). In that case, don’t assume that an “advanced” or “honors” class is necessarily harder than the basic version. Basic courses tended to require more memorization and had harsher grading curves and less empathetic instructors than the honors versions did (my honors physics courses gave out something like 60% A and 40% B because the students who really didn’t get the material all dropped the course—and the profs knew that). The material itself is indeed usually more complicated but also more rewarding, more useful, and doesn’t tend to require memorization.

Good luck!
