Transport Canada has compiled a partial listing of weak knowledge areas based on examination data from January 2008 to January 2009. Examination topics with a success rate of less than 50% were considered to be weak knowledge areas.

Of course, the knowledge standard for the PPAER is 60%, so this listing is sure to be incomplete. Nonetheless, it provides us with some useful guidance.

You should conduct a thorough review of all weak areas listed—including the ones from licenses/permits you are not applying for. It’s a pretty safe bet that weak topic for one license/permit is marginal for another license/permit even if it isn’t listed.
