At the risk of causing a little thread drift I think there's a fundamental issue with the way these exams are conducted.
That is to say I consider that the exam paper, along with the associated questions, should be returned to the candidate with their score clearly marked. This allows the candidate to more clearly determine where they went astray, or not, and effectively allows a peer review of the entire paper - and marking methodology.
To my mind this could only be a positive thing. Sure one could get the occasional person who may pursue something that they clearly don't get, and are a pain in the process, but on the whole I think it would give a great deal more integrity and better 'buy-in' to the process than is currently the case.
Personally I have not asked for any recount but was interested to note that on my CPL tech exam some years ago I received less than 100%. The resultant KDR indicated a deficiency in an area that I could probably lecture on in University. As it happened I recalled enough of the question to know that my answer was, from first principles, arguably more correct than the one they (presumably) were expecting. Perhaps they weren't expecting an instrument designer to take this exam, and in this case it didn't affect the ultimate outcome, but if I had been on the verge of passing it would have been particularly galling, and would not have accurately represented an assessment of my ability/knowledge of the subject. After all if it doesn't do the latter with some degree of integrity what's the point of the exam in the first place?
So back to the thread, pragmatically I'd say resit it, but if you've got the dosh and feel strongly enough that you've correctly answered something they say you haven't (and recall sufficient of the question to be sure of it) then go for the reassessment - and ask for your paper back with the question(s) concerned.
Yes I realise it's electronic know so it would be the electronic equivalent of paper you'd ask for! Also I imagine they won't comply with the request for return of the information but that doesn't make any refusal right
, and one day someone is going to pursue that refusal through the courts (or political circles as needed) - more power to them!
