So, because you're from California, 29 sounds typical. Its a lot of money and a lot of work, but that's the price you pay for living in the state with the hardest med schools to get into.
I'm from Washington, so I kind of had to apply to a bunch to watch my back as well. I put 20 down on AMCAS, but I already eliminated 2 that I'm not interested in anymore.
My friend from Alabama only applied to 2 last year and got accepted to her state school no problem. A cousin in S Carolina also only applied to 2. But they live in those states.....
