Most schools have some provision for this. Your best bet it to check out the school(s) you would be interested in attending if you decided to pursue a degree. That way your courses will count for something, you'll gain insights into the particulars of the school/program, and can sometimes work to help improve you application if you do apply for a degree program.

Are there many schools out there that will let you take a few graduate level courses so you can test the water without being enrolled? I've heard taking these classes can help boost chances of being accepted to graduate schools.
