Maybe he just wanted comments on the course as a whole, or the exam itsself. Maybe he is just a wanker. If your can't flay them with your facts, baffle them with your bullshit. That is the ONLY way to get through any school Jon. Sorry, it is a fact of Academic Life. There is no other reason I recieved full marks (except for maths) during my "educating seasons".
You need to learn to "play into the game"...it is not easy, but it is an aquired skill. Think like a parrot....Repeat After Me......
Self-Important teachers/professors are abundant in Colleges, and they want to remain Self Important regardless of whether they know anything or not. Actually, they MUST remain self important in order to retain their postion, so they must be appeased. So appease.......just to get the piece of paper, then you can go your own way.
Bite your tongue for a while even if it is difficult.
