<p>Many premeds major in BBB (Biological Bassis of Behavior). It is a bit more lax than bio and accepts more premed courses towards your major requirements. Penn is a great place for premed. Most other top schools are great too. Penn provides you with great opportunities as a premed for advising, research (very easy to start working at a lab freshman year), and clinical experience (HUP and CHOP have a lot of premed volunteers).</p>
