Transport for London is currently conducting some roadworks at the Mill Hill circus multi-lane roundabout, so you need to be extra careful when approaching this junction which used to be controlled by traffic lights.
There is now some pedestrian lights on the southern approach, but normal roundabout rules apply on the other approaches.
Get enough practice on the A41 dual carriageway and joining Mill Hill circus both from the Broadway as well as Apex corner.
