Favorite classes taken??

<p>Just wanted to know current/past students at NU which classes or professors really stuck out to them. I'm majoring in chemistry or biological sciences but it could be in any area. Are there any classes/professors that you should not leave Northwestern without taking?
Thanks!</p>

<p>Some popular classes:</p>

<p>History of the Holocaust
Intro to Russian Literature
Human Sexuality
Modern Cosmology</p>
