The test is okay, but there isn't a huge amount of medical-device-specific stuff in there. That's understandable if the intent is to keep the test generic for students from all backgrounds, and strictly-speaking there aren't that many differences between ISO9001 and ISO13485 anyway.
Risk management and software validation are two key additions, and both are tested.
However a knowledgeable ISO9001 auditor isn't automatically a knowledgeable ISO13485 auditor, so I would have liked to have seen a few more (and punchier) ISO13485-specific questions nonetheless.
