Also I don't know if you're physically in Canada right now but you should consider speaking with the local anesthesia programs and their chief residents.
The board exams in Canada typically rely on lots of old questions which every single years class dutifully remembers then regurgitates onto paper so that the incoming years can benefit. Not that I would ever do that 🙂
If you can get your hands on that absolutely key stuff you'll have an idea how it compares to your own training and knowledge.
As you can imagine this is frowned on by the Royal College so use your discretion.
Also they will be studying and doing questions for the exam and will have organized study groups and would love to have some attending help for some of the questions.
