PILOT TRAINING in UK, WW2
I believe that, in general, most flying schools stuck to the rule of awarding up to one third of pilots and navigators commissions, based on assessment and examination marks. I met some officers who had not been even to Grammar Schools, but had done well on their courses. Some sergeants had been to very good schools, but had not done well in the wings exam, or had been ill at the end of the course. At all events, some seemed to be at the mercy of some strong minded or dominant CGIs or CFIs. I knew one Oxford Graduate and a tutor at the University, who had to receive Maths coaching from an elementary school master on the course, as he could not understand Spherical Trigonometry for Astro Navigation. fredjhh
