<p>I was trying to plan out what classes I would ideally take this fall, but was very confused by the numbers following the department code. For example, for Intro to Public Health it says 3283 after, so I was wondering if that meant anything, like it's not meant for freshmen or something. There are no pre-reqs listed, so I wasn't sure. If someone could please explain the numbering system to me that would be great. (sorry if this is a very silly request)</p>
<p>As a rule of thumb: the greater the leading digit of the course number, the higher level the class. However, as you have discovered, not all the higher number classes necessarily have prerequisites.</p>
<p>so it’s possible to take intro to public health as a freshman?</p>
<p>To the best of my knowledge, if there are no pre-reqs, then yes, you can take it.</p>
<p>Yes you can take it as a freshman, but you might not get in. The class is capped at 300, and there are already 34 people on the waitlist. As I understand, it’s not one of those classes that a lot of people drop.</p>
<p>For reference, 308 people took it last fall - the cap was not raised from 300. That means those extra 8 were specifically added. I can’t speak for the public health department, but chances are that means that they’ll give preference to some people, but not all. I doubt freshmen are going to be given special privilege.</p>
<p>I took econ 401 my first semester, so yes you can take anything you want if you satisfy the prereqs and have room.</p>
