The form is very confusing if you haven't done the Irish system. It seems like the upper form can be used for GCSEs, the lower for A Levels, but we don't have the A1 A2 A3 etc. grades and there's no way of specifying that you're talking about junior cert (which I believe is GCSE equivalent) in lieu of higher cert (which is officially 2/3 of an A level). Even without that problem, the names of the subjects I did at GCSE aren't in the dropdown menu (My school didn't do individual science at GCSE level - it was science and additional science). I'd stick it in the 'other education' place, but I have a degree to be talking about too!
Very confusing form. It's not a case of 'the form filters out the idiots', it's simply that the form does not provide the answers required.
