Taking a university course while on TN visa

Hi,

Does anyone know whether you can take a university course while on a TN visa? I would like to take an interest course at UCLA, but am not sure whether you can do that while on a TN as i understand that a TN is for work only. But if the course is a non-degree course, and i'm not in school full time, does that still count?

Thanks!

As long as it is not a second job, I don't see any reason why not.
