People really are getting lazy these days. There is a huge difference between a gleim book and a copy of a systems test at an airline. If you think about it, your aircraft manual is almost the same as having a gleim book. The gleim has all the info for passing your test as does the aircraft maunal. You cannot compare having a cheat sheet to a gleim book. Yes, having the test sheet may give you an edge for taking the written, but how are you ever going to pass the rest of training or even recurrent if you don't have good knowledge of what you are doing. Take the time a learn what is required of you! The people we are carrying expect nothing less. Do you want brain surgery from a surgeon who took the easy way through med school?
