IMO the quick responses go to the people who check the "currently employed by a 121/135 carrier" box. I submitted mine a few months ago and got a response the next day. I don't work for XJT---but from my experience at my airline. Study flows/limitations every night, and take it in doses.
One guy in my class put it best.... 121 training at XJT/AWAC/etc. is not a sprint, it is a marathon. Believe in the system----they have thousands of pilots that have successfully completed their training programs because their system works. By the time the checkride/oral comes along--all the pieces will have come together and you'll walk out saying... how the hell did I do that?
Six weeks goes by fast---before you know it you're sitting up front and you hear people boarding behind you, the door shuts, and everything you learned in systems, indoc, sim, profiles, etc. all goes into effect!
