<p>You need to contact the college or university that you are interested in, and ask about enrolling for one or two classes in “non-degree” student status. Other names for that status might be “non-matriculated” or “special” student.</p>
<p>If you are able to enroll in that kind of status, you will have to pay the full cost of the course on a per-credit basis, and you will receive real college credits that are transferable. If you do not want to receive college credits, you need to ask if it is possible to audit the class. You will probably still have to pay the full fees, and you will receive a transcript indicating that you audited the course, but no grade will be reported.</p>
<p>Some colleges and universities do not allow anyone to enroll in classes in a non-degree status, some only allow students to enroll in certain classes in that status, and others will allow non-degree students to take any class that they have the pre-reqs. for and are willing to pay for. You really do have to investigate this yourself for each place on your list.</p>
