There are bona fide reasons for this policy.
Wot, like propping up the CAA policy of generating highly ambiguous exam questions and preventing this policy to be undermined by a public discussion?
The entire reason that instructors are not supposed to discuss actual questions is to prevent the reconstruction of the PPL question bank, which leads to effective revision aids like the PPL Confuser.
The funny thing is that ATPL cadets (hey, you have two ex cadets in the front of the 747 you fly on your next holiday
) have the question bank in its entirety.
