Next year I graduate with my BFA from my local university. Here's some pointers:
See if you can get a certificate or associates from your community college during your time there. I went to a community college for 2 years (and two summer semesters) and by the end of it I had finished nearly all of my gen eds (my degree required 3 upper level courses, so I opted to take them at university) and I had an associates in Liberal Arts. It's not much more more than resume padding, but it's something. An option you could pursue is getting an associates or a certificate in a computer science field of your choice, while taking biology/science classes for gen eds. It'll give you a glimpse at what both degrees are like, and will let you make an informed decision before you start bank rolling some real cash at an accredited institution. Hell, you may be able to land a good job with the certificate. On the job experience is worth more than a piece of paper, the piece of paper just gives you a step in over your peers. But if you can get in the field without spending big bucks, take the opportunity.
Don't take classes just to take them. You're paying for this shit. Maybe instead of comp 102 or whatever, take poetry, or something you think you might get something out of. Instead of calculus, try stats, etc. This last year I was thinking of taking a film class for a humanities credit, purely based on the fact that I like movies, and it was online so I could probably just BS the whole thing anyway. Instead I took Linguistic Anthropology, and even though it has no impact on my major at all, that class enhanced my view of the world significantly. It was definitely more work than an online film class, but it was much more worthy of my time and money. I felt good taking it and studying it.
#1 thing I got out of college is a broadening of world view and connections with people who have the same goals as I do. Having peers and professors I can rely on to talk with about my study, recommend me for jobs, present me with opportunities from places I wasn't aware of, etc., is one of the things that makes college really worth it. Don't be afraid of not fitting in, or not making connections, as you'll be spending at least 2 years of focused time with a group of individuals who have the same goals as you. College has a way of bringing people out of their shells, you'll ease into it very naturally.
This may be conjecture, but your reasoning behind your educational pursuits seem a little flimsy. You don't have to write at length about it on the skial.com tf2 gaming forum, but I feel like I should mention it. If you want to succeed not just in college, but in your career after college, you have to have a real passion for what you want. No one really explained this to me in high school, but half of success is literally just wanting to do it, if that makes sense. But of course since you're still in high school, you can't really get an understanding of what you'd want your life long passion to be. Most people never do. That's why I'd really recommend taking
@Zeo up on his offer to chat with you, or anyone else you may know in those fields. You can learn alot about the degree and yourself based on your investment in those conversations. Maybe you get a cert in CS, took some bio classes, but when you get to university you want to try something completely different. That is completely fine and natural. Just be confident in your decisions and don't be afraid to explore.
If you find yourself at a loss, not really passionate about anything, literally don't do it. There is no point in going into debt for a useless degree, anchoring your life to a field you chose due to the sunk-cost fallacy. As long as you live your life with a personal passion and drive you will not be a failure, no matter what the people around you may think. College is what you make of it, and if you aren't gonna make anything of it, don't waste your time, money, and resources. But if you do decide to go, go with a passion that drives you towards personal growth.
