Test (with lingots)
Would be helpful to be able to check answers after completion rather than just be told the score
Perhaps, but that's simply not what it's there for.
(For that matter, when I did my certification exams in Cornish, I only got a score back -- I wasn't told which questions were right or wrong, nor did I get told the correct answers or even get my own answers back. I think that's pretty standard for certification tests.)
