Philosophy Test

Wow,
  today I found out the result of an all-night study session on contemporary moral theories.  I thought I was going to blow it out of the water.  I got an 89.  I asked my professor if there was anything I could do to bring it up to an A-.... nope.
  I think it was a result of not coming into school with the right skills/game-plan and engaging at a high enough level.  I've turned the heat up in the past couple weeks and saw the results of it in my last quiz (100).
  Note to other veteran scholars or any adults with a break between schooling-  go harder than you think you need to from the very beginning.  It's always better to be way better than fall short.
  I'm lucky that my professor has the same exact class an hour before this one.  I have a break and try to sit in on it as often as possible.  I hear things the second time that I might have missed the first time.  It gives me the opportunity to formulate questions and apply the principles to my own thoughts.
  I know an 89 isn't terrible, but it grinds my gears to know that other kids did better than me.  All I can do is go harder and see what happens with the next test.
  It will be over the morality of war.  Naturally, I'm in a better disposition to do well on it.  I just can't slack off at all if I want that A+.
