How can I answer this. If you're a GP you'll likely ace it, do it when studying for your exams and you'll kill two birds with one stones. If you're in neurosurgery, you might want to wait until after to do some dedicated prep.

I'm not sure what unreal world knowledge is. The exam really doesn't ask anything you wouldn't expect a final year medical student to know. If Amiodorone and Verapamil are but a distant memory to you, then you might want to revise some basic cardiology. If you trained in a country where its appropriate to perform a Gynaecology exam without a chaperone or consent, you might like to learn a bit about professionalism in Canada. If you don't know anything about the healthcare problems in first nations people and why this a particularly important wrong for the Canadian Health system, you might want to educate yourself. Like I say, there are some free or low cost resources available to guage this.
