Congrats. I was a bod and only managed to get only one question wrong in my Air Law exam and to be honest didn't find it too hard. The confuser went a long way to helping me pass even if a couple of the answers given in there are actually wrong!
I think with any exams, especially where safety is concerned you should fully understand the subject otherwise it defetes the object. You can cram and probably pass with the confuser alone but then you will only have a surface knowledge and could put yourself and others at risk. For example if you don't fully understand airspace classification then you could end up in BIG trouble! Just a thought!
