I did the ATP written prep course at ALL ATP. They offered a discount for furloughed ALPA members from my company (at least at the local site in KHEF).

It's a boring day, but pretty easy and the pass rate is very good. I had done a bit of studying over the years with the gleim, but the prep gives you "everything" that you need to know.

Essentially you sit in front of the computer for as long as you can tolerate and look at questions paired with the correct answer (only look at the right answer).

The thought is that if you can recognize one of the two, your brain should be able to pair up the other part of the pair (either the question or answer). Most of the time when taking the test, I found myself just looking at the answer choices and picking out the option that was familiar to me.

IIRC, I think I got a 94% with 2 questions wrong (both flight planning questions that I didn't want to complete so guessed at). The whole process took me about 7 1/2 hrs. (showed up at 9am, studied till noon, went to lunch for an hour with another furloughee, studied from 1 until about 330, then took the test from 330-430.)
