Okay, you failed. Well done. You managed to get good answers perhaps for only one or two questions and that is really really bad if you are indeed a real world pilot. Aviation knowledge must go beyond simply memorizing and knowing. The safety of your passengers and yourself depends entirely on whether you truly UNDERSTAND it all. A blind man can read braille, but it wont mean a thing if he's illiterate. You maybe know some of the basics, but entirely lacks the understanding. Sorry.
