It certainly pays to check your work! I just took a huge science test. I checked it over twice before I turned it in, and I got an A! My score was 94 out of 100! I figure that each time I checked it, I found half of the mistakes that were there at a time. What would have been my score if I had not checked my work?

  1. 6 mistakes after 2 checks means that there were 12 mistakes after 1 check.

    A big bad 24 mistakes if you had not checked it: 76%
