Thanks Harry. We have an online exam for tech and another for SOPs with every LPC (PPC) at my current employer, but you can print off each question unanswered to research it at your convenience. It's a little wasteful on paper, so best to turn up early and print it in the crew room, but if yours won't allow a similar approach, then it is a bit of a pain. Personally, for the time it takes, I just do mine at home. An couple of hours is all it takes to do our tests with a bit of reference to manuals for a few questions. I hope your exams aren't made so obscure that you spend much more time than that searching for answers.
