I'm confident you're a better judge of the worth of A-levels than the people who've never even taken them furiously insisting they're objective indicators of merit, and not high school syllabus-recollection/essay-writing tests which are easily taught to, actively fudged by some schools and greatly variable in actual difficulty from one subject and exam board to another.

Still, your grades (and mine) pale in comparison to all these youngsters with an opportunity to get A* grades...
