<p>This link has been swimming in CC waters for a long time now. I don’t think it’s relevant. Yes, math, physics and philosophy are generally considered to be difficult majors. But explanations as to why people who major in them score slightly higher can vary. For example, one can argue that students who are smarter in general are more attracted to these majors. In any case, the frequent advice college students receive when they ask what major prepares them best for law school – major in whatever you like the best – still holds true, and it would be really stupid for someone to disregard it just because of a table like this.</p>
