National Boards

Oh wow this is a day I hope I dont have to repeat.  However I feel like I might.  I took the National Board today and it was awful.  I am exhausted.  My brain hurts and my legs hurt.  I went on a very long walk when I got home.  I felt like there were so many things I didnt know or I could have narrowed the answers to 2 then couldnt get it past that.  It was just mentally draining and maybe thats why I feel so bad.  Hopefully it all works out.
