I'm thinking of taking cles soon but I'm not sure if the curriculum is the correct one for me..?

I already have a Bachelor's degree (in a different subject) and the program at the school I'm thinking about attending is actually for an ociate's degree. I've heard good things about this 2 yr. school, which is why I'm interested. But I don't know if it'll bolster my resume any, if it displays that I earned a Bachelor's, followed by an ociates (in another subject matter of course). There's another local school which has cles in this same concentration of study, but offers a certificate after completing the coursework. That would make more sense. The downside is till recently, I never heard of the school. So, I'm not sure what its reputation is. Is it odd for a person who graduated college to go for an ociate's? I'd appreciate your input.
