They've changed the course so much that it feels like a scam. If you answer the questions wrong, they lock you out and expect you to reregister and pay again every time, no matter where you are in the course. I was emailing with them and they were very quick to reply, until I ask for a refund. Twice. They stopped answering. There's nothing in the fine print when you pay that says this will be the case. Horrible business. Do not recommend. Find another course that doesn't try to steal money from you.
