FYI people...I never got an email invitation for my test (I checked spam and trash). It just showed up in my tracker. When I talked to two IRCC agents twice, they told me, yeah...that happens sometimes, and the system is glitchy. They then told me to take the test using the link, and I was able to. So, not everyone receives the email invitation for the test, which is really problematic because if I hadn't checked the tracker, I would have never known about the test, and I would have missed it. I really hope this doesn't happen with the oath invitation.
