sure, you could say you've been taking come courses, but be ready for questions (or probes) in that direction. try to have some answers ready for the most obvious questions?
of course, it's easier to do if you actually have been taking courses. i dunno if that's the case for you.
in my experience, managers are more often interested in why i left my previous job, instead of the gab between jobs. i tell my current manager i left because schedule conflict with school, which couldn't be further from the truth.
