If as reported the pass rate for A level examination entrants is in the order of 97% why wouldn't most employers expect a candidate to have such a qualification as a matter of course ?
It has not always been the case in the past, but I would expect to see it become more of a minimum educational requirement for employment in the future.
In a market that is awash with low hour licence holders, you would be selling yourself against others with such minimum qualifications.....wouldn't you ??
