best thing to do is to simply learn the rough idea of where everything is.
eg: know the layout of the CAR
Vol1-maintenance
Vol2-licensing
Vol3-day to day stuff & ops
Vol4-schedules
do the same for the CAOs and for AIP
Aip:
Enr1.1-navigation and ops
1.2-VMC stuff
1.4-airspace stuff
1.5-IFR stuff
1.6 transponder
1.7 altitude info
1.10- flight planning etc
Do this and u can knock the exam out in 2 weeks
