Yesterday in Math

Yesterday in Geometry, I learned that even when I think I have some lessons "down pat" I can still fail a test miserably. I took a test and I received a 10.5 out of 20. But I'm going to look at the glass half filled. At least I got more than 50%. The worst part about is, is that my teacher doesn't let us do test corrections like the rest of the Geometry teachers do. whore !
