Due to time constaints I just learnt the answer bank at the back and also the variables like how many hosties and fire extinguishes you must have.
I had done a bit of IFR flying so the plates were not a problem although there is a bit of RTFQ so looking at the sample questions on the CH plate etc would be worthwhile.
Spent two nights after work looking over it and got about 88%.
Most of the exam questions are word for word whats in the samples.
