Today I passed my CHUF after a 2nd attempt.
The CHUF can really be difficult if you have not understood the concepts regarding TEM especially.

Before the CHUF I would definitely make sure to read:
-CAAP 5.59
- https://www.skybrary.aero/index.php/Threat_and_Error_Management_(TEM)

In regards to the Bob Tait book, make sure if you dont understand something or answer a question and get it right without completely understanding how, treat it like a KDR and look it up. In my exam I got some questions in relation to diet (what is good to eat and what isn't), Active Listening and what it is, scanning for traffic and visual illusions.

Thank you to Bob and everyone for the help over the past couple of weeks regarding Human Factors and for providing us with such great study material!
