<p>On the other hand girls graduate HS and apply to college in significantly larger numbers than boys, and significantly more girls applying to college have high HS GPAs and are vals/sals/top 10% of their HS class.

Because more girls apply to college, on balance girls probably have it a little tougher.</p>
