Hi Pat,
There are so many options out there, it depends what kind of course you're looking at. I did a night course (C&G) years ago, which was a great introduction to black and white photography. There are countless technical courses available.
I'm now doing a degree in Wildlife Photography and there's a straight photography course at my college too. These aren't overly helpful in the technical stakes, but great for concepts, commercial, finding your own style etc.
If you find a good tutor and make sure the content of the course is relevant to what you want to learn, it can surely only be a good thing!
