I have seen some creative writing courses and certificates offered online by colleges. Of course, many of these rarely have openings (otherwise I would probably be in one right now). I'm wondering though if it is worth it. I do love to write and am working on a novel - I wonder if a course or two related to completing a novel or long work would help propel me to finish it as I've been stuck in a rut for a while now. Any advice? It is a lot of money to spend without a career at the end of the line.
If you think that the benefits are going to outweigh the monetary costs then I say go for it. If you really think it will help you finish your novel and if the classes are reputable, I say go for it. You could try out some cheaper classes first, like through a community college or a free online tutorial.
Like Auriella said, if you think the cost/time/effort to take the class is worth the (possible) end result, then I think you should do it. If, however, you think you could get the same results from joining a critique group or doing some free workshops, then maybe it's not worth it.
I think that a creative writing course is definitely worth it. There are so many areas that you can specialize in if you have a base in writing, especially if you are working on writing your own novel! I think it would open a lot of doors in the writing field.
