Aeslin doesn't need a muggle college degree, or even particularly want one when magic is much more fascinating, and she knows herself well enough to doubt that she'll stay in this small college town more than the few months (at most) her current project will take.

But, enrolling in a couple classes is a handy way of getting access to campus.  It's got a very interesting leyline intersection, and a building whose stones look like they might have come from a rock-nymph.

She springs for an apartment off-campus, of course.  The dorms would be closer, but she doesn't want to have to hide things from a muggle roommate.

It's not too long before she comes to the limit of spells she can unobtrusively cast during class hours.  She can still study the leylines decently from her apartment (for a while), but the stones are limited to one place.  So, late one night after all the other students should've gone to bed (or to bars or other places off campus), Aeslin sets up right next to that stone building, with her wand and chalk-and-crayon circles and spare staves and books and everything.  Soon, magic rainbows are flying in the air between her and the building in very interesting ways - and very visible ways, should anyone happen to walk by.
