I don't think memory items will help. Most of the IFR flight questions ask you to compute ETA, estimated fuel burn, and mach number required to reach your destination in a certain amount of time.
The aircraft specific questions all involved "refer to figure" then ask you to compute things like T/O distance, landing distance, power settings, CG, etc...
I didn't really study the aircraft specific questions and was able to pull off a 95% using the Gleim.
