Sheppardair is the way to go. They keep up with the bank of questins that the FAA is using at this time. If any changes are made, they have to publically let it be know and Sheppard find out and adds the new questions. I used their program, studied for a few days and got 100%...pure memorization. You will get to the point where you get have way through the question and you know the answer is B.
