The answer is so obvious it's stupid. There are two tracks -
1. get your ratings on the outside. Figure out what colleges you like, compare the girl to boy ratio, and pick the school that has the highest female to male ratio.
2. get your ratings at a school that has an aviation program. Again, figure out which one has the best female to male ratio and apply.
Where you get your ratings, or where you got your degree, ultimately doesn't matter.
