don't forget the field lines

SO I rocked the Physics exam from a few weeks ago. 19/20. I had to argue for the last mark as I wrote the answer in the wrong place. That was good. So I have 92.5 in physics midterms, 75 ish in labs. and less than 2 weeks till exam nd I am a little scared. I am going to start sleeping on the floor. It makes my back feel better and it's not comfortable to roll over and go back to sleep when my alarm goes off at 6:15. Or 5.

[ the field lines are important. They are in sport anyhow.]
