IREX Practice Exams
Bob Tait’s IREX Practice Exams are designed to build the two skills that matter most for IREX success: strong theory knowledge and reliable exam technique under time pressure.
Each module gives you realistic, CASA-style practice using randomised questions from a large question bank. As a result, every attempt feels fresh and helps you identify weak areas before the real examination.
Start with open practice exams at your own pace. Then move to a timed exam completed in one sitting to simulate real exam conditions. After each attempt, you can review your results and answers so you can learn from mistakes and improve your accuracy.
The IREX Exam Prep gives you a realistic preview of what to expect in the CASA examination. It includes four online practice exams written to a standard comparable with the aerodynamic and instrument-rating questions used in CASA exams.
You receive three untimed exams to complete at your own pace, plus one timed exam that must be completed in a single sitting once started.
Each exam can be submitted once, and you can review your results after completion. In addition, extra exam attempts are available for purchase through the online store.
IREX Video Classroom Lectures
If you can’t attend a full-time IREX course, the Bob Tait Video Lecture Series gives you a flexible way to keep progressing. Study at your own pace, pause and replay lessons, and revisit difficult concepts whenever you need.
You can purchase individual topic blocks or choose the complete IREX video course.
The IREX Video Lecture series contains many hours of video material to help you prepare for the IFR theory exam.
