I have 6 GCSE's at C grade, no A levels, and no degree.
My 1st attempt at the CAA ATPL Nav subjets I did not even get a partial pass, on the second attempt I received a partial and complete the 3 outstanding exams on the 3rd attempt.
My CAA Tech exams I received a partial on the 1st attempt completed the 2 remaining exams on the 2nd attempt.
I found at was a quantity issue, cramming all the work and a lot of b*ll!!!!! into my pea sized brain.
I partialled passd on my I/R first time, and completed 2nd sitting on the 1st series.
I now fly the B757 and am a flying instructor.
You dont need degrees and qualifications coming out of your ears to get through it, just pure determination a wanting to do the job and of course some flying ability.
