Just passed the IREX and thought that I would share some of the techniques that I used that I would have wanted to have access to before my exam.

The exam overall is very similar to Bob's practice exams. Expect to get 2/3 questions on each of these topics LSALT, sector entry, fuel calculations, holding/alternate requirements, and bearing/intercept questions. The exam is also full of questions where the answers are in the AIP, part 91, 61, ERSA, or DAPs.

1. Read through the textbook once. Take notes if you want. Just get familiar with terminology...
2. Take a practice exam at the start of your study so you can see how the exam is formatted and what is actually relevant to your study.
3. Go back and work on the questions you got wrong. Don't try to find videos online- there aren't any at the moment. Go back to the textbook and take your time going through the topic you struggled with, and do all of the practice questions so that you can fully understand it and turn any weaknesses into strengths. (Also check the common errors section on the CASA website)
4. Do as many practice exams as you can and make sure you get to know the DAPs, ERSA, AIP, and part 91, 61 like the back of your hand- probably at least half ( I say closer to 60/70%) of the answers to questions can be found in these documents. Also, put tags in the AIP and ERSA, 15 and 5, respectively.
5. Make a "cheat sheet" of formulas, weather conditions, icing temps, or anything you struggle with, and practice writing it down so that at the start of the test, you can write it all down and not be stressed trying to remember that one thing during the exam.
6. Learn from your mistakes, find the nuance in the question, and use that to your advantage. An example would be the unreliable altimeter question from Bob during an ILS where, instead of going around, you can just switch to the LOC approach.
7. Read the question and the answers slowly and properly. Don't make silly mistakes.

This probably isnt great advice but you really dont need to know that much about IFR flying (or even the VH-OZY fact sheet) for the IREX, You just need to get really good at knowing where to find the answer in the permitted materials, and then you only really need to know the stuff about weather etc that you can't bring into the exam.

Good luck,
Thanks Bob couldnt have done it without you.
