It isn't that hard! Aerocourse know most of the tips and tricks, but expect the weather questions to refer to time periods that are just on the changeover periods for the GFA charts. You will get 6 of those, to be referred to in groups of 2.
Also be quite slick with your E6B
There may be some practice questions on the Transport Canada website, or at
www.aerotraining.com.
Good luck
