Exam is a flawed but fun little mystery that has enough original ideas behind it to keep it going pretty nicely for the most part - but then predictably doesn't know what to do with its ending.

An opening credits montage of each of the candidates sets things up very impressively indeed, and although it has to fight past two or three pretty sub-standard performances, a delightfully slimy and smart-arsed Luke Mably and a suave effort from Jimi Mistry cancels these out.

Far from perfect and with one or two gaping plot holes (they have some pretty strange interpretations of 'don't ruin your paper') but still pretty good.
