Last summer when I was doing my writtens there was a lot of fuss and bother about questions and answers being posted up on the net. Personally I had a quick look at some of them and treated them with a LARGE dose of salt.
For what it's worth my advice is to ignore stuff trawled off the web, pay attention to the lectures and get your groundschool to clear up any points you're unsure of.
I was at Cabair and the final mock exams and debriefs were worth a massive amount more than anything scanned onto websites.
As I say that's just my opinion but it sure worked for me!!
