I'm actually getting worse at this. I started off by getting 90%, then 80% and the last mock paper I did resulted in a poxy 62%. Some intense revision is called for I think!
The type of questions that typically catch me out are along the lines of 'a balloon flying at night shall carry a red light that shows in all directions suspended 5m/5ft/10m below the basket.' To which my answer is 'who cares how far below the basket it's suspended - just don't fly into it!'
There is so much that is irrelevant to the kind of operations you expect to be doing in a light aircraft - if you can't see the point of knowing something, you tend to not retain it. Oh well, just have to suck on it if I want to fly without a guardian angel I suppose.
