My interest was piqued by this article, but upon initial investigation, I'm having trouble stomaching putting $50 toward learning how to use github... Any reason I shouldn't just skip ahead?
You can still take all of the courses for free and get a certificate, but Coursera won't validate that you actually did the coursework.
I'm guessing you could pick and choose to pay for only certain classes, but you have to pay for all of them to earn the overall "Specialization" certificate.
