I know exactly what you mean. I have failed section 7 twice and have absolutely no idea what I did wrong.  The first time I failed I only had two suggestions on studying. The second time I had four so I think I got four questions wrong.  Funny sort of, since I feel like I know the "real world" banking and tools inside and out. 

Yes, there are trick questions here. This is not a test of skill. I am sorry I have no advice for you but I did want to share that I feel your frustration too!
