For those of us still waiting for the call, getting the rust brushed off as several have suggested (DC8, 744, et.al) has not gone unnoticed.
The intel that has been gained as of this writing shows that there are plenty of questions generated from that grand ATP Test bank that has been cheerfully taken by all.
Taking the ATP RED BOOK around is not my preference----I have fallen asleep with it too many times. For IPAD Users I just found PREPWARE ATP software by ASA for $9.99. Not too expensive and you can select the areas you wish to strengthen/remember. For example, I have seen no intel asking and Weight/Balance questions in the 100 question test.
For me, it is very helpful...YMMV. Along with my White Book that is a compilation of all of the other stuff, I have not been bored with this process.
I hope this is helpful for those still waiting the call.
