Danger Will Robinson!
Practicle exams are the pits.
We recently had one using 3 of 4 different kinds of CGI languages, no-one passed it because you have to remmber the syntax perfectly in 3 languages to get them to run. Lecturer said he wouldn't pass students unless 2 of the 3 answers ran!!! All the students complained and the lecturer got in trouble with the exam board for running an exam like this and we were graded on our assignments and homework instead. (luckly, phew!)
At least if you only have to remember one language it might be possible. Just keep coding until you know it back to front.
