Syag, I assume that there is some correlation between the number of girls and the number of slots, and I also assume that people tend to apply to enough schools to give themselves a shot at getting into one. Otherwise, according to your math, only 13% of girls would go to seminary.
Based on those assumptions, it would make sense to apply to six or seven seminaries, but at the very least three. If all of your ideal seminaries agree that you’re not for them, then maybe it’s time to find some new ideals.
