Humor, we were in the exact same boat. I was shocked at all the kids I knew from home who were stellar students in high school just go ape shit and either fail out, got booted from the university or just flat out withdrew to regroup. I skated through freshman year by the skin of my teeth. Had to retake a class or two but I survived and got better each year (of my 5 total).
I stayed in Columbus after college and also have some younger relatives in school now and who graduated recently. The university is really changed and the students seem to be of higher caliber...or at least not act like they're connected to cartels. It has a totally different vibe to me...which is great because my diploma keeps looking better and better.
