You've been offerred numerous tutorials on this subject matter by various readers (including RoB columnists) and if you fail to go to "class", how can you possibly expect to pass the exam? 
You pose the same questions over and over again. The reality is, the answers to your questions don't really matter to you or otherwise YOU would make an effort to understand this subject instead of asking for handouts. 
My sense is that the only reason you want someone to hand you answers is so you can disagree with them and the facts never matter (to you.)
