I suspect EGBK = TROLL,
If not my sympathies to the instructors.... No doubt (if) he/she gains a licence we can expect to read another chapter of the EGBK chronicle published by the AAIB at some point in the future.
There is a "fantastic" instructor who could help -
FAA Training - BFR FLYERS
I seem to remember his post echoed the thoughts of EGBK when he was learning to fly!!
