if you get a nice guy youll be fine. i fully stuffed up my reversing when i sat it, like not even close to the driveway, but he ticked it off and said "you've got the general idea"

i went backwards but that was bout it. definately don't speed, but also watch you dont go too slow, 40k in a 50k area (unless you're stuck behind someone) can be interpreted as a lack of confidence. good luck!
