mikeHotel152,
Those not academically gifted might learn the questionbase, but in order to understand the 14 ATPL subjects properly, you DO need to have the intellect to pass several A levels. Problem is that nowadays, most FO 's do not have a clue about the ATPL theory, and as a result their Airmanship has been compromised since groundschool
Get back some strict academical and psychological entry tests now! Eliminate the questionbank, replace the multiple choice by open questions and oral examinations and we will quickly see an increase of quality in the cockpit. The rot always starts from the basement...
