Luck with A&P II

I thought I would elaborate a little more on my A&P II class because it is not easy by any means.  This class has been strange for me.  The first test I had no idea how I did and did well... same as the second and third, but this last one I thought for sure I had a C or below.  I usually start by going through and answering all the questions I know.  I did that and I thought I knew 34-36 of them out of 50.  So, I was expecting to have a 68-72 on this test.  When I went back through, I still had no idea on the questions I skipped over.  I tried crossing out answers I knew it couldn't be, but it didn't help much.  When she said we had one minute left and to finish up the one we were working on, I had five.  I made my best guess and turned it in.  The questions on the test were completely confusing.  One question was about someone drinking 6 glasses of wine...they wanted to know how much urine output would be and the concentration.  I remember one of the answers being 4,000 ml... which is 4 L... which is like drinking two 2 L coke bottles!  My first reaction was that something had to be wrong with a person if they did that!  Second was that she said input had to equal out put and exactly how big were these glasses and why wasn't this person dead from alcohol poisoning?  All of these questions were running through my head because I had no sleep at all the night before.  I usually do not sleep that well the night before the test because I end up dreaming about what is going to be on the test, but this time it was different.  I had gone to print out my homework and it would not open!!  There were only ten questions, but each question had four questions built into it.  So, that is what I did all night.  At the end of class the teacher will go scan the exams and if you want to see your grade you can.  I bolted for the door.  I didn't want to see it...I thought I knew what I had, so why rush it?  Well, I ended up with a 90?!?  How this happened I had no idea!!  I have decided that I should become a professional multiple choice test taker.  I have always been good at problem solving and reasoning, but this is insane.  I have been so lucky with it this semester it is unreal.  Because of my luck, I have now officially started to play the lottery...lol...when I remember to buy a ticket that is : )
