Yep I struggled with that one to. POF isn't much better. Also found MET difficult as well. Struggled through MET at ppl level and found the shear volume of information to be daunting.
Generally people tend to find the wordy or touchy feely subjects like Ops, Comms, Air Law the easiest as they can be rote learnt. Radio Nav is a weird one as some of the subject matter is basically out of date and you are unlikely to come across it in your career. I enjoyed the more practical papers such as flight planning and general navigation as I could get my teeth into them and actually see that I was learning something that I would use.
I found the Bristol ATP website to be excellent. If you use it then don't leave it to the last minute before you start going through the questions. In some subjects like MET there are nearly 1,000 actual JAA questions in the database.
As a skipper once told me - knuckle down and think of the ATPL's as a right of passage.
