Update for KAS995:
I completed my citizenship test on July 31st but after a long time wait I got nothing news. Then I applied GCMS to see what happened. On the GCMS it said my test had unusual activities and the result was NOT accepted by IRCC.
Actually it was because my laptop (Dell Inspiron 15) camera driver was not compatible with their online test system. It worked fine when I present my ID and PR card to the camera but it said "not camera found" when the test started, and it jumped out of the test automatically. I tried a lot of times then I found their a three drivers in Chrome for the only one camera. I tried the third one then it worked then I completed the test in five minutes. However the system recognized it as "unusual activities". I wrote a mail to IRCC Calgary to explain the whole thing but they still did not accept it and scheduled a video test by MS Teams to see if I can really pass the test.
On December 2nd, I went online to see the officer on time. It was a nice lady. She asked me to confirm all my information not changed and checked every single page of my passport. Then she showed me another screen with a slide had 20 questions. I read and selected the answers of the questions one by one, then she said I got a full-mark and congratulated me for passing the test. After all she said I was in the queue for waiting oath ceremony now. The only thing I can do now is just wait.
