When i was applying for schools, I was worried about the same thing. but i'm now a freshman, and my channel wasn't brought up at all during the whole process. You'll be golden dude

Dont delete it for the wrong reasons

xJrockandjrollx wrote I'm worried that a college might see some of the stuff I do (lots of cursing at games) and not accept me. Should I just delete my channel to get it out of the way? I have somewhat of a base but obviously I can quit at any time. I like YouTube as a hobby but I don't want it affecting the rest of my life.

All they care about is your money. What you do outside of school does not matter, as long as you have the money to attend you have no worries.
