I assume that you're still in high school.
There are a lot of things that make it fun. Living in the dorms is super fun (18 year olds living on their own for the first time = super fun times). Do it if you can. the people that you meet are really cool. You can join a frat, join ultimate frisbee, etc. there's just a lot of things to do. You could join a pre-med organization, but I always felt that too many of those members were more concerned with putting a title on their resume than doing anything.
you also get to take classes with other people that were at the top of their schools. you get to see how "pre-meds" act like. you'll see how some are cut throat and then friendly to you if they think you can help them (they usually become nicer in your 3rd/4th year when they realize they can't get into any professional schools with their grades)
.
overall, you could just go to a CC, get good grades, apply, and get in (2-3 years depending on courseload and summer school and if classes are full or not. there are budget cuts, so some classes are reduced). you'll just be missing out on the fun experiences that you could have at a 4 year college.
if you really want to grow up that fast, then more power to you.
