I made good grades. Here in the U.S. you pretty much need a 3.70 average or better (grades where I live are usually on a four-point scale, with 4 being an A) to get into med school, and the best grades need to be in science and the pre-med courses. In college I had a 3.87. In graduate school and for my other post-graduate degree, I had a 4.0, but they really look harder at the undergrad grades, at least according to what I was told. Then, of course, you have to make a decent score on the MCAT tests. All in all, it's possibly more trouble than it's worth.
