FAA to Canadian ATPL conversion
Unfortunately I cannot offer any better advice. I find myself in the same situation, however I take comfort in the fact that the test is no more than 20 questions long. I friend of mine took it and missed the first time around, but was successful on the second trial. I suppose when it comes to preparing for that exam the best thing to do is what you did: study the old fashioned way by reading all available relevant data.
