Well, there is no risk to you with my 30-day money-back guarantee. What school do you know of that would allow you to enroll in their program, show up to lectures for a month, learn the material, and then receive a full refund? Or what instructor do you know that would teach private lessons for a month and then give you a full refund? Not any that I know of.
I call this my "Swipe My Secrets Guarantee" You could join the program, learn a bunch of my secrets, and land-paying work, AND still ask for a refund. I know you wouldn't do that, that's not how we 3d artists get down, but I'm willing to take that risk by offering this guarantee so you rest assured that you are making one of the best decisions of your life.
