Gday rob the price hike absolutely sickens me
From memory rob some of the cp / pnr questions that I got were from reporting points, not just aerodromes. In answer to your question I will only tell you do what you think is best for you as I would hate you to fail on what I have said but I used old out of date ones & got through a bit silly I know but really could not afford it at the time to replace them. I also found that erc (H) were not req'd in this exam,also done the same in planning however erc(H) were req'd. This is only my experience use it as a guide only, others may be able to help more.
GOOD LUCK
