<p>My section of 215 had about 50. This was an odd year in that 215 wasn’t split into two sections; there are normally two sections of about 25 each fall and a section of maybhttp://talk.collegeconfidential.com/princeton-university/1122556-mathematics-princeton.htmle 15 in the spring. My 217 section has 9 (there’s another section with 23), and 218 has 16 students this spring. You can get more numbers here: [Course</a> Offerings « Office of the Registrar](<a href=“http://registrar.princeton.edu/course-offerings/]Course”>Course Offerings | Office of the Registrar). Just click the MAT button and search; it will tell you the enrollment in each class. You can change the semester as well to look at things over the past four or five semesters.</p>
<p>And jasapo, that isn’t a list of top-five finishes; it’s a list of winning schools. Princeton has 13 top-5 finishes since 1990, third behind Harvard (19) and MIT (14). Also, someone edited Princeton out of the table of Putnam-winning universities on Wikipedia. We won Putnam in 2006.</p>
