I suck!

So this morning my SS class 3 came back and i did 2 quads. I declared an exam on them and missed like 8 spots! I've never missed 8 spots in my life, and of course it was on an exam. Then she had to leave early for another appt so I'm sure I still missed a few spots. I saved a quad to use as my mock board if I need to, but I'm hoping I will find a better candidate before then. She'll be hard, plus I haven't taken pa's of the quad.
