I used ALLATPS for my CFI-I and MEI checkrides and found them usefull. I did not go there to learn to be a CFII or MEI, I did that at my FBO. But they did a fine job of getting me to pass the checkride on a set schedule. I paid a premium for that service, but I found it usefull.

My impression of thier career program is that it is also priced at a premium, and in 90 days you're not going to learn how to not kill yourself with your shiny new tickets.

ALLATPS is the best career program I'm aware of.
