Don't click too much (pray and spray) but DO click when you see something which MIGHT be a hazard - lady with a pushchair, person on a bike, man in a white van etc.
Remember, you click AS you see something which COULD be a hazard (Let's them know you've got your eye on the ball) then you click again when it actually turns in to a hazard (Let's them know you've taken action and altered speed etc).
It's odd - I never felt confident with it, on my car and bike test, but both times i've scored very highly. I think it's because you get zero feedback until the end.
You'll be sound tho mate.
