<p>Hey everyone, I'm hoping to transfer to ucsd with the environmental systems earth science major and have a quick question regarding the major prep. The ucsd website suggests that esys majors should complete Mathematics 10A, 10B, 10C, but Math. 20A-B-C for the earth sciences track. Why is it that math 20 is suggested for earth sciences but not the other esys tracks? What problems will I run into if I take 10A-C?</p>
