Depending on what kind of college you go to, yes. I went to a community college for two years then to a four-year college for the second two. At a community college they'll let you take pretty much anything they offer (though they'll have a narrower range of classes, e.g., my community college didn't offer linguistics classes) but you'll probably have to either take a placement test or show some SAT or other test scores if you want to take some college level math or science or things like that. And if you want to transfer you'll probably just be taking general education classes which will eat up most of what you'll have time for, probably. Going right to a four-year school, well, I didn't do that and I don't know how it differs, but the people who went to my college as freshmen when I transferred as a junior had to take some core classes their first year to cover the same kind of general education, but they could also get started on their majors more easily, particularly if their majors were things that you'd normally only find at a university, like astronomy (beyond the very basic stuff - like my community college had just an "intro to astromony" class whereas my university had a lot more including one I took which was a history of astronomy).
