Thanks Bumble, I knew what they were, I just couldn't find a name for them, there I was trying to find something all fancy in Latin or Greek and it's plain English and under my nose all along.

I'm trying to resist using the mid bucks guides for now, there are some changes to the syllabus for 2012 that seem to be missing and while I like using it as a revision aid I also like to find the information for myself if I can.
