course load of 8-12 (quarter)units, with max 1 science course, doesn't look that great to adcoms. Also try to spread out your GE's so that you don't end up taking 3+ science classes every quarter for the last 2 years. Just fyi, I was done with gen chem, calc, gen bio, phys, and ochem by end of 2nd year. I'm listing these courses because they are mostly required courses for d schools. This way, I felt like I could mix GE's with upper div bio courses and not stress out.
