How the INRAT works

Common questions

Is it a subscription?
No. IFR is a one-time payment of $99 CAD, by card through Stripe. Nothing renews and you are not charged again.
What do the 3 months cover?
Every chapter, chapter quiz and INRAT mock exam in the IFR course, with its charts and diagrams, for 3 months from the day you pay. When they end the course locks again, and you can buy another 3 months if you need them.
What if I don't pass?
If you write the INRAT and do not pass, we give you 3 more months of IFR, free, once per purchase. Write the exam while your access is active or within 30 days after it ends, and email us from your account’s address within 30 days of writing it. Otherwise all sales are final, unless you were charged twice or by mistake, or the law requires a refund. Refunds and the pass guarantee
Which devices does it work on?
Any phone, tablet or computer with an up-to-date web browser; there is no app to install. Your reading place, quiz scores and unfinished mock exams are saved to your account, so you can switch devices.
How current is it?
The study content was last updated on 3 October 2026. The INRAT format on this page was checked against Transport Canada's TP 691E (Seventeenth Edition, 2013) on 19 September 2026. Every answer is explained and names its source: the CARs section, TC AIM paragraph or TP study guide it relies on.
Is this a ground school?
No. TC Exam Prep is study notes and practice for the INRAT. It does not replace the training your flight school or instructor gives you.
