Also emergency stop is a maneuver I think, I had that also on my test, I had reverse round the corner to the left, they are two types of corners, a sharp corner 90 degree angle and also a gradual bend which takes more concentration, it will be likely that one, because you can't do a full lock on the wheel and go for it whilst doing your observations you need to be looking and turning the wheel and opening the wheel at the same time as looking around.
