Well, it's always a good route to take if you don't want to get stuck with a minimum wage job. You can go somewhere without any secondary education, but not nearly as far as you can with a college education. Also, I don't believe you can get a master's from College.
The advantage of college is that it takes you only a few years and you are already specialized, as opposed to university which is much broader.
Oh, you'll need to chill on the teacher thing... it's not like highschool at all, the teachers there don't put up with crap from their students because they don't really care. If they pass, they pass, if not, they know there are more people willing to do the work. It isn't like that in all cases, but college profs aren't pushovers like some highschools teachers are.
