<p>Twenty years ago there was a widespread belief among students that nearly all colleges had intro science courses that were purposefully intended to weed out aspiring pre-med students. I don’t know if that ever was the case, but today I don’t think it is.</p>
<p>These days, however, there are far too many kids who mistakenly believe themselves to be M.D. material (or more likely pharmacy school material), and they weed themselves out because they can’t master an introductory chemistry class that isn’t trying to do anything more than teach them some basic chemistry.</p>
