No. I didn't do the math. But if in the summer a student took a day job working retail, a night job at UPS or Federal Express, and waitered on weekends during the school year, he could put a pretty good dent in it. Plus it would keep him out of trouble and from spending money.
I made it through engineering school working two hours a day M-F but not on the weekends (which I spent with my girlfriend accomplishing "nothing"). I had an easy summer job as a camp counselor, but could have easily worked a second job instead of going out and drinking with my buddies.
