<p>What exactly do you want to know? Pre-med is just a set of ~10 classes anyone can take. UCLA has more students since its public as well as more asians. I believe UCLA has the most applicants to med school of any university which equals more competition, someone will have to find that stat for me. Pre-med classes are fairly large at USC. Biology ranges from 200-350 people, Chemistry from 100-200, Organic from 100-200, Physics from 50-100 and Calculus is ~60.</p>
