<p>I'm visiting Harvard and staying on-campus with a friend for a couple of nights, but I wanted to ask a quick question as to what classes I would be allowed to sit in, or where I'd be able to find this information. The replies from the Admissions Office to my inquires were depressingly inadequate, so any help I could get here would be great.</p>
<p>You have a couple of different options. You could probably just sit in with your friend on some of his/her classes, especially in any larger classes where one more student won't make any difference. The second option is what I did. While my daughter was off attending her pre-frosh overnight and going to classes with her host, I sat in on classes also. The admissions office provided a list of about a dozen classes that were open to visitors. I don't don't know whether they provide such a list year round, but they had it during the post-April 1st school visiting season. Ask at the Admissions office.</p>
<p>hmm...probably ask the advisors of whatever your intended Major is.
lol. yeah, the admissions office does provide [beyond] inadequate answers. I sent them [an] email[s] in the last few months, and got back vague answers.</p>
<p>Talk to the friend you are staying with he would know. It is incredibly easy and you don't even need to talk to anybody if you're sitting in on a larger lecture, if you are in a class with say, fewer than 40 people, I would go slightly early and ask the professor or head TF if you can sit in on the class and I doubt they would say no. Any harvard student would probably know which courses you wouldn't have a trouble sitting in on - big science courses like Life Sciences, Chem 27, Physical Sciences, you would have no problem.</p>
