I've always been bored by education (in fact I left high school halfway through) and college will probably be no different, not to mention there are subjects where I am dumber than a tree (math for example) so I'd probably fail most exams just because of that.
As far as my work experience goes I've been a developer for a year but was working as a technical advisor for a mobile phone retailer before that - the job was actually quite nice but unfortunately the pay was nowhere near enough to sustain myself and the company had pretty scammy sales practices so I left.
I failed Calculus I twice and they basically had a B.A. degree just to graduate me. You can do it, and it's worth it. A moderately priced state school will have a decent-enough CS department, and what you'll learn there will help (as a senior/staff-level engineer, albeit a consultant these days, I do use what I learned in school quite a lot), but what's more valuable is the humanities and the general rounding-out-as-a-person that happens at college.
"Oh, I need to go join a trendy startup" is a pretty good way to stick your foot in a bear trap. There's more to life than a keyboard, as you have seemingly realized--college is a very good way to find out what (and, if you work in tech, there's no need to go broke doing it; I had my entire loan package paid off from my university by 26 because I didn't go to some crazy school).
If nothing else, you should explore it more seriously than "well, high school bored me." The experiences you get at college are really hard to replicate outside of it.
