That’s a good, fair question.
What I generated above was a list of <em>100-level</em> (Introductory) Princeton courses, showing 8 out of 282 with enrollment sizes of 100 or more students. (Alexandre had stated that "at most private research universities, Ivy or not, intro-level classes are large (over 150 students) ")</p>
<p>So let’s broaden the definition of “Intro”.
Here’s a list of 200-level courses:
<a href=“Course Offerings | Office of the Registrar”>Course Offerings | Office of the Registrar;
<p>In that list of 219 records, I count 7 courses with over 150 students.</p>
<p>CHM 202 General Chemistry II
COS 226 Algorithms and Data Structures
ECO 202 Statistics & Data Analysis for Economics
HIS 212 Europe in the World: Monarchies, Nations
MOL 214 Intro to Cellular & Molecular Biology
PHI 203 Intro to Metaphysics & Epistemology
PSY 208 The Brain: A User’s Guide</p>
<p>If you are asserting that, in certain popular fields, many introductory courses are large even at the most selective private universities, then it appears you are correct … if Princeton is representative, if 150 is our standard for “large”, and if 7 (plus the 8 100-levels) is “many”.</p>
