Lets hope his second one went ok. Undoubtedly failed for the examiner having to take control, and for not showng pilot in command judgement to manage the situation better. He could have asked the examiner to take control or simply to ask to leave the circuit for a few minutes of straight and level or whatever he needed, but very hard to make that call in a test and very easy to struggle on and hope for the best. Doubly worse with the pressure of an expiring theory test. The uk doesnt brief on this before the test as far as i know, and undoubtedly should do as it would have helped. In the usa, in the preflight brief it is clearly explained that you can simply ask for a discontinuance if you feel ill, and any time the examiner is forced to take control it is indeed game over.
