Sparkly, I am sure you are well-intentioned and honest in bringing your question here, but it should be abundantly clear to you that you will get several people who see you even setting foot in a college or university as the height of pritzus, citing kol kevodah bas melech pnimah and several other sources; on the other hand you will hear from several who believe you make the best of it and seek guidance on how to behave in such environments. You won’t get a clear answer.
At the end of the day, though, Use your Yiddishe kop! If you feel that you dont have self control, find some or change your environment. If you do have it and have the blessing of your biggest supports, your parents, then go ahead and don’t listen to the naysayers.
I may be making an assumption, but your parents invested in educating you Jewishly. have the respect for them and those who built the schools you went to, and use what they taught you!
