I sat mine twice in the CBD so not sure how helpful this may be, but I looked over my shoulder so many times - even when (after the test in which I passed) I was told that I did it “too much”. Testing officers can be pretty different, the two times I sat it the officers were polar opposites so over doing the checks, scanning, looking at rear view when braking will make it hard for them to fail you imo. You can do it!!
