I recently completed my CAF aptitude test last Monday, July 16, 2018.
For those wondering, the actual aptitude test was much more difficult than the samples provided (as stated right on the practice aptitude test). The sample is simply there to give you an idea about the structure of the exam, not the actual difficulty level (so keep this in mind when preparing).
In regards to the pass/fail questions I've read regarding the aptitude test, the Sergeant I spoke with following completion of the aptitude test informed me that the test is normalized and your score is placed on a bell curve. What this means is that your raw score DOESN'T mean anything, but it is compared to the overall average of every applicant to the Canadian Armed Forces. Thus, the average is in the middle of the bell curve, and given the designation as the 50th %ile. This means that you are right in the middle of the spread (50% of people scored higher, 50% scored lower). So in that sense, there is no "pass or fail". However, your normalized score will have an impact on a variety of factors. Firstly, if you score significantly lower, your application will be less competitive compared to your peers who scored higher overall. Additionally, certain occupations require specified values. If you are lower than the designated value, you will not be eligible for the occupation you applied for.
This was my understanding of it anyway. Hopefully that makes sense and clears things up for some of you.
Best of luck, everyone. Study hard and hopefully i'll see you at BMQ in the months to come.
Cheers,
