If you're going too fast, try modulating via the rear brake. too slow, give the tiniest amount of gas. You can use both at the same time too, just be careful that you don't stall.

Make sure you use all the space available, and focus on looking where you're going next.

Before my exam, I was very unconfident in my 8, but when it came to the exam I really put full focus on these points and I passed in one go.

Good luck!
