Sounds like you're gonna fail out of college if you go in as comp sci. I was pretty much like you.
Almost happened to me once... I bombed the first semester, found out comp sci wasnt my thing and I only really liked computer games. Even though I did well in AP comp sci programming, its hard to pass the course if you dont attend classes.
7 friends in comp sci during freshman year, now only 1 survived.... I'm chem, 4 info sys, 1 psych and the remaining one graduated HS early and is gonna graduate ahead of us as well...
If you want to cop out of doing comp sci in the middle, go with info sys... no offense info sys majors..
