I'm not sure if this will be any help whatsoever but last year London JAs results came out on Thurs 12th June. (Our email did anyway - DD1 had auditioned for a Y6 place).
Dd reported very similar exercises but her improvisation involved pretending to be in a pillow fight (with feather pillows naturally). Think they had fun with them this year!
Am completely new on here but thought I'd mention (as some people have asked on this thread) that we have just received our Mid Associate result for London by email. Ours was a "no" - entirely expected and no drama fortunately.
Best of luck to everyone waiting.
