Deferring costs a student $250,000+ in future income. An unfortunate mistake, but I'm sure the 17 are grateful to have been accepted.
Actually, I'm not sure that math is exact. With the interest you save from not taking out an extra $50,000 in loans, in addition to the money you could make working that entire year, you probably won't be losing as much as you'd think. Though, you may very well make more your first year as a doctor. But the emotional benefits of having a year off between undergrad and medical school (if that's your scenario), all the while knowing your accepted (oh, and you don't have to worry about paying for your first year) is near priceless. It'd be tempting for me. I'm so sick of school.
