Ah geez, sorry my answer's a bit long, but I hope some of this can be a little helpful!
First, recognise that college isn't a necessary given -- and I say this as someone who went to art school and really enjoyed it! Really consider whether art school is the best choice for you. This article talks about some alternatives, if it isn't something you'd considered, and I think it's a good read even if you ultimately decide to go.
The thing is that college is really expensive. For comics, webcomics especially, the ~DREAM~ is that you're makin just enough to live on your own and pay your bills. A simple degree might help for getting a day job, but as far as art education goes.... it might make sense for a doctor or a lawyer to take out huge loans, but it doesn't make sense to take out huge loans when your hope is just to make a modest living doing what you love.
I have a very dear creator friend who wanted to go to SCAD and study comics like I did, but her parents couldn't afford it, so she ended up going to a state college with a terrible art program. She didn't enjoy it. Her final project was a museum installation, it couldn't have been further from what she wanted to do. But now she's being paid a good wage as a colourist on a webcomic, she's the lead artist on a new virtual pet site, and she's setting up to finally publish her own original comic in book form.
I studied comics for four years at a major art college in a very good program, and she struggled through a terrible state art program, and yet we're equal in skill and both getting paid doing what we love. College doesn't make or break what you can do, as long as you're always drawing/creating, making contacts, and willing to learn. Art jobs rarely need to see that you majored in art -- they just want to see your portfolio.
But if you're confident that you can afford it and it's right for you ---
These are rare, but they exist! I majored in "Sequential Art" in college and I've seen other colleges offer a "Cartooning" major! But anything that improves your skills in draftsmanship and composition will translate in some way to comics, honestly. Even if it's not an exact match to what you want to do.
Every college is going to be different! For example, in our school, when people wanted to become illustrators or concept artists, we would always encourage them to quit their illustration classes and become a sequential art major instead, even if they didn't want to do comics --- because the illustration classes at our school never really taught you how to improve your drawing skills, and sequential classes would make you draw a LOT and teach you tons about composition and drawing well and quickly. But that was just my school -- other schools might have a really good illustration program!! Animation might be really good..... or it might shuffle you into Maya classes that don't translate to drawing skills at all. There's not gonna be a single buzzword you can watch for, it'll be different from school to school.
My advice is to visit the college you're interested in, and if you can, talk to professors or the people who run that department, and see if they make you excited to take their classes. Or when you've chosen a college, if you don't have to declare your major right away, go ahead and take a couple classes in the majors you're considering, meet the people who are in that major, and see if it's a place you fit in.
In my experience in art school, the best judge of which classes are going to be the best fit for you is actually... the people. My peers who were taking illustration classes but fit in better with the sequential kids would eventually express regret that they hadn't taken sequential classes instead, because illustration had never really been right for them. Kids not liking the people in the architecture department was the first red flag that maybe they weren't going to enjoy the architecture program. One architecture friend who felt that way took a photography class on a whim and suddenly discovered that, despite the fact that she'd never planned to major in that, she LOVED it, and ended up graduating with a beautiful portfolio as a commercial photographer.
So basically I guess... look for a place you can afford, because art isn't going to pay off massive debt, and look for a program that really excites you..... but if you do end up in classes that don't help you, or if that's the most affordable option for you, remember that that's not the end of the world either! The fact that you're here learning from other artists is honestly one of the biggest and most important part of making it as an artist! The only other part is just to keep creating as much as you can and pushing yourself to be better and better.
