If you have already purchased their ATP software, they will give you a discounted rate on the regional Interview prep. If you interview and call them back with feedback from the written, they will refund your money. Call and ask those questions, they will be honest about what their software is good for.
I took the TSA written, I had seen 99% of the questions ahead of time.
With their other courses, I also took the mil comp commercial + ATP + CFI + FEX over the course of about a month, and never scored less than a 98 on any of them.
They are plugged in. Always a good idea to call and ask questions. Even ask them about where to go to take the ATP or translating military flight hours.
