<p>How are college professors when it comes to sitting in on classes? I want to sit in on some grad math classes, so how would I go about approaching the professor for that without him/her laughing at me. Or do I have to pay to attend classes at that school.</p>
<p>Well, if you want to get credit then yeah, you have to pay. But I think just observing is okay if you ask the professor beforehand.</p>
<p>Do you think it would be wierd to "obverse" for a whole semester?</p>
<p>I think what you want to do is "audit" the class. This means that you go, but do not have to do the assignments or take the tests and you do not get credit. Contact the admissions office or registrar for more info - don't go through the prof if you plan on doing it the whole semester.</p>
<p>If the class is big enough I doubt the prof would mind you "sneaking in" or even notice you. After all, soo many students skip certain lectures (at least at huge public universities) that the prof might actually like it if someone who didn't have to be there wanted to be just to listen. I doubt the prof would laugh at you if you decided to ask him/her.</p>
<p>I dont think graduate math classes are very big. I would be pretty noticable, especially since i would probably look younger than the other students.</p>
<p>If you are genuinely interested and you can show have actual ability in the prerequisite material, I think any professor would welcome you warmly</p>
<p>You can always leave a tape-recorder on, in your seat and tape record the whole lecture. Some people do that.</p>
<p>hmm. that'll be tough if the professor says: let us refer to this diagram. We can see clearly that...</p>
<p>Besides, that could very possibly be illegal.</p>
