You may be able to find out a person's trade or classification from their profile, if they've filled it in.
I am one of the pilots on this site. There are several others.
As I see it, you are setting yourself up for continued failure by your attitude and lack of understanding.
Aptitude testing has been used for decades to give a reasonable indication of applicants' abilities to successfully complete their training. They are not done purely for recruiters' recreational purposes or to antagonize BrianBB. They are not perfect, but they are a better indication than any given applicant's opinion of him/herself, you included. Regardless, nobody cares what you think about these tests; we only care that you pass it, and preferably without whining. The only thing that counts on this test or any other is passing.
Many people that pass this one go on to fail somewhere later down the path. Some people fail this first test who may have actually successfully completed the entire training programme eventually. A line has to be drawn somewhere, though, in order to save far more effort and expense by skipping this step.
It's also not about you or any other individual. The CF pilot training programme does not exist to train people to be pilots, it exists to train pilots for the CF. It serves the CF, not you. The CF does not care if BrianBB ever becomes a pilot, only that it has enough pilots trained to a given standard. This is an important distinction that you need to understand.
The people whose judgment and opinions that you are questioning here are the same people that you would have to work for or with, or be trained by, should you make it into the CF. You should listen to what is being said. Any heat that you are receiving is due to the way in which you have communicated. To be blunt, I am not impressed either.
Spelling and grammar are important in the CF. Clear communication is essential. Mission success and lives often depend upon it. You will find yourself judged by your ability to communicate, and a higher standard is expected of officers. Because most of us here are or were CF members, we therefore expect that from people here, too. Also, if you do not care to put the effort into communicating clearly and effectively, we would also not expect you to put the required effort into other important areas either.
