Can I sit in on a class?

<p>If there's a class I want to take but I don't want to spend my credits on it, would a professor typically allow an interested student to sit in on the class? And would I be able to write papers, take tests, etc. for that class (since there are actually a few classes I'm looking at that I would like to write papers for, just for fun)? </p>

<p>I'm not in college yet, but going through the course offerings and major requirements, I've realized that there are lots of classes I wouldn't be able to take for credit due to certain restrictions but that I would still like to take (stuff like philosophy, religion, music appreciation, etc.).</p>

<p>Thanks!</p>

<p>It depends on the prof and the class. Generally, in a large lecture class, a prof won’t even notice, let alone mind an extra body in the room (although he or she probably isn’t going to want to grade your papers or tests.) As a courtesy, you should ask permission to sit in. In a small, participation oriented seminar, it might depend on whether the class is full or not, how the prof feels about auditors generally, and whether they know you and want you there even if you aren’t signed up. In this case, you definitely need permission to audit.</p>
