All you need to do is memorise bristols question bank for each subject until you get 98% or above. The caa will use feedback for at least 70% of each paper and often a lot higher than that eg comms and law.This basically means that you can guess the rest and still pass and if you know anything you should get over 80% +. so my advise to you is to do 50 questions per day in each bank and then blitz it on weekends.Bristol got a huge grant to set up the question bank.THE CAA DO USE IT.
