TCAA to FAA ATPL (A or H) conversion exam

[pneu]

Has someone wrote the ATP Transport Canada to FAA exam recently ? Either A or H. I was wondering what kind of questions are in the test ? I was told it’s a total of 40 questions, all about air law, but while working through the Dauntless ground school app, it seems that any/all subjects can be asked (physiology, weather, Perf, WB, etc…).

Is it indeed air law only, or a mix of various subjects ? Any other recommendations would be greatly appreciated.

Thank you for your replies.
