Reverse parking is assessed on control, accuracy, observation and consideration for other road users.
You should control the vehicle smoothly and keep effective all-round observation as the front and rear of the car move through different arcs.
These examples are for understanding and practice; they are not a promise that a particular mistake will always receive a particular grade.
Focusing only on parking reference points and missing a cyclist or pedestrian.
Allowing the front of the car to swing toward another road user without sufficient clearance.
