<p>(The following are not absolutes for all, but there is enough of a tilt to make the numbers totally believable and understandable.)</p>
<p>First, many girls do not take the most difficult courses in order to get a higher GPA. Our valedictorian and other high-ranking girls who had almost a 4.0 took four majors instead of five, refused to take physics or anything else considered difficult that could ruin her cum (in our physics class, C was a good grade - one guy with that grade went to Johns Hopkins and excelled. I also find that boys get marked down if they are a little difficult to handle while more compliant girls sail through.</p>
<p>Second, boys excel in logic much more than girls. It is true objectively, and the well-publicized gender gap in politics where women accept the most illogical and nonsensical arguments would lend huge credence to that. Guys would ask how having more people on healthcare with many paying nothing would reduce costs for everyone. Think reductio ad absurdum. Girls would say we just have to care more and it will all work out. That mind of muddled thinking will not bode well for you taking the SAT.</p>
