<p>First of all, a 3.3 will leave you with a low chance of getting into ANY med school. Instead of worrying about what caliber of med school you will get into (they all offer excellent medical education), you should be worrying about just getting in.</p>
<p>Secondly, med school would prefer to see you focus on a few solid activities rather than spread yourself too thin doing too many activities.</p>
<p>Thirdly, a B/B- median in science courses is normal, even at supposedly grade-inflated colleges. Med schools don’t really care if your school is hard or easy. I personally think differences between grading at different schools are overblown anyhow.</p>
