I got a cycling proficiency thingy too, did it when I was about 9 or so I remember beinig really stuck on it because they gave me this map of the course to look at overnight the day before the test, and I didn't understand a word of it, and my parents were away on business and couldn't explain it to me. Its a miracle I ever passed My brother failed his though!
Anyway, references.. they were seriously annoying me when I was doing my dissertation. Mainly for the reason that I was told to put them in places where I thought for myself, and was then told to reference where I got that idea from. Not the easiest thing, really.
