Earn while you learn?

Have you ever tried to learn anything about search optimising and affiliate marketing? Why don't you try to join a program that let's you earn while learning? I saw an advertisement on Digitalpoint that a program named Affilit was one of the companies who render service to put their students in a unique way of learning on how affiliate marketing and search optimising works, and get paid? We'll, it's obvious for me and if we pay through their course, and they will pay us back for just learning? It's like we're still learning for free and did not earn anything but to spend money and they return it immediately? Ahahaha! It's too impossible for me, and do you think they will gain profit which we send them money to learn the course, and get paid for our own money?
