You realise the requested exit is already behind you.
The route mistake has already happened. The next question is whether you keep it as a route mistake or turn it into a driving one.
Missed the exit: what next?
Do not cut across lanes or drive over road markings to rescue the planned route. Maintain your lane, comply with the signs and lane arrows and follow a legal route from your present position. On a standard single-lane roundabout, continuing round to another safe exit may be possible. On turbo roundabouts, lane separators and mandatory directions can prevent circling again.
What the examiner can assess
The navigation error alone is different from unsafe driving. The critical behaviour is whether you respond legally, remain aware of cyclists and pedestrians at exits, indicate appropriately and avoid forcing a last-second move. The CBR Rijprocedure B discusses positioning and observation on roundabouts; it does not require you to save every route instruction.
Not all roundabouts work alike
At a roundabout with separate cycle tracks, check the signs and markings that determine priority at the entry and exit. Do not assume every cyclist automatically has priority. At a turbo roundabout, the correct lane usually must be chosen before entry and may be physically separated: never cross a raised separator or solid arrangement to reach the missed turn.
Practise the recovery, not the route
Ask your instructor to give an exit instruction after you have already entered a roundabout. First identify your present lane and permitted exits. Then continue legally and let navigation recover later. Practise the same decision on both a conventional and a lane-guided roundabout.
