Interesting. In '63 only 5 O levels required which for me were 5 standard grade school certificates as I was in Nairobi. Went to Aden for medicals and arrived at Cerney in Apr 63. 5 standard grades seemed to be OK as I went on to ETPS and ended up on the staff. So academic qualifications were not the only requirement. In fact I recall Brawdy becoming known as the Graduate Exit Scheme due to the chop rate!
