Debbie....I don't think you can ever take enough classes. I do it all the time and will be finishing another certification in August.

There might be other ways you can achieve your objective. Is it the degree you want, or the knowledge? If it is the knowledge there might be other programs -- through associations or the like -- where you can get the knowledge without having to take all the classes required for a degree -- some of which may be of no interest to you. And you might save some money!

Go for it!
