All the very best of luck. As someone else who spent two years training thanks to the vagaries of our great British weather I know how you feel. Just try to relax as much as possible and let the training take over.
Ditto the comment that the CFI wants you to pass. Just be sure to point out anything that you do wrong once you spot it. It helps highlight the fact that you know you did something wrong and simply went about correcting it.
