I don't know much since I've only just joined but I have my doubts. It says free course and then on first sign up, the site requests my card details. I mean, I understand that it's probably to properly motivate us but I have to at least sample what I'm paying for, see if it's worth it. I logged off without completing the sign up and was later sent a kink by mail to join without card details. I thought OK, that much better but the class I attended was a webinar with course materials that I have to pay for. The certification that the ad said was free turned out to come for a fee also. It's a bit much though, these are my thoughts on the matter right now because the truth is the add said professional certification for free, that's what got me. I didn't have to be deceived to get my attention.
