    Hello,

     

    I wrote a test which was too hard. I do not want to use the Canvas redistribution method because my scores are not distributed equally across the range; and I cannot add an equal number of fudge points because I do have some scores near 100%. The method that would make the most sense to adjust for this test is the square root method.

     

    I think the best way to see how it works is to run the numbers on one of your own tests; here's a sample of resulting scores from mine.
