That would work out to be a failure rate of 77.2% which is pretty high for day 1. I know that the theoretical knowledge needed to pass the maths & physics sections of Oxford's tests does not extend beyond GCSE level (16 years of age in the UK)
Day 1 is not only maths and physics. These are supposed to be the easiest parts. Oxford's tests are based on "360 assessment" I can say. Correlating the results of the tests they provide "COMPASS TESTS" to every mental and motor skill needed to make an airline pilot. COMPASS tests can accurately assess these skills that someone might simply have or don't have.
The pass rate for day 1 with GAA is yet very poor vs. UK pass rate which is usually 60-65%.
And yes.. around BHD50,000
