Yup, a snow day.... that's why I suggested that you bring your math book and review home.  You WILL have a difficult time writing grade 10 math without reviewing a good variety of questions including: algebraic equations, the normal curve, box & whisker plots, and graphing.  I provided review sheets and provided plenty of opportunity for extra help - the rest is up to you.  Make sure you have a ruler, a calculator, a couple pencils, and an eraser.  See you Monday morning (exam day).
