The Ragged Edge...

I have reached the ragged edge.  Since Friday, I have crammed a semesters worth of Physics into my brain.  I have taken over 20 pages of notes. Worked numerous physics problems.  Hauled physics books back and forth to my duty and back and forth to work and home.  I have studied a ridiculous amount of time.  I have completed the final exam study guide.  I have gone to two real teachers and said, "explain this so I can understand it" too many times to count.  I am exhausted.  I can barely think at this point.  Tomorrow I will walk into a physics class and begin to review a semesters worth of material that I struggle to understand myself.  I think I now have a decent grasp of it, but my confidence is shaky at best.  I don't even know if anyone reads this, but if you do, send up a prayer for me over the next several days that I can convey the material correctly to these kids.  They deserve that.
