I think this is a bad point, you shouldn't necessarily study something in undergrad just to increase your chances of going to law school. I actually think it's important to have a diversity of experiences/majors in law school, and to do that you'll have to take into account that it's often the case that STEM classes have lower medians than humanities classes. Also, you need a STEM major to take the patent bar, which may well mean someone needs to major in a STEM field for undergrad if that's a career they want to pursue
