Make sure you know the old whizz wheel inside out and you will be fine. Know how to work out map scales (if you have a 1:500,000 chart how many miles does 15 inches represent?), be competent with the 1 in 60 rule and be comfortable with UK 1:500,000 charts, symbols etc.
Get the triangle of velocities fixed firmly in the brain and the wind problems will be a piece of cake.
Hope this helps
