Yeah, I got my PPL while in college. Was lucky enough to have tuition, room, and food paid for by a scholarship, and it turned out the pay for working an overnight ambulance shift was almost exactly the cost of an hour of training in the local CFI's Grumman AA1B (and then, when that finally died, Tomahawk). I tried to work a shift or two per week (more in the summer) and flew an hour or two per week. I started this scheme late Junior year and took my checkride the summer I graduated.
