I am sitting at work between Xmas nad New year- this is proving to be a great time to revise Nav <img src="wink.gif" border="0">
My method is the write it down as you go one - yep, you end up rewriting the book, but I find it helps with understanding rather than just learning the facts.
The confuser is definately a huge help, although I have to confess to feeling a teensy bit guilty about using it. Especially when questions out of it actually come up in the exam...
Still - gotta get 'em to go flying!
