Well, I applied to 24 schools and that cost me $850 in AMCAS fees. This does not include the $80 average fee for secondary applications, of which I recieved 20 or so. That puts close to $2500, not including interview transportation and accomodations. BUT, the thing to keep in mind is that this sum pales in comparison to what 4 years of medical school will cost. So, in reality, it's just pocket change...
