I have to decide today whether or not to sign up for an online course for a certificate program that I'm taking. I didn't take a course this past semester because of money, but I'd really like to take the copy-editing course that starts tomorrow - I can put it on my visa, and I should be able to pay it off in three months, but I will end up paying some interest on it.

I think having this course on my resume will good for jobs that I'm applying for, so there's that, plus my interest in it. The only downside is money - and I have to decide today.

What should I do?
