<p>Are all Pratt students required to take Chem 21L, if
you do not have an AP Chem credit?</p>
<p>I believe it's Chem 21 or 23 (most will take 21 if they do not have AP credit).</p>
<p>All Pratt students must have one semester of Chem credit as part of the four natural science credits required for the major. Two semesters of Physics (including at least one taken at Duke vs. AP) are also included. For the fourth NS:
BME - another chem
ECE - bio 25 or equivalent
CEE, MEMS - any qualifying NS (list of disqual. courses at pratt.duke.edu)</p>
