How do you figure grades on a 35 question test?

Answer 1

Assuming that you want a percentage grade, you'll have 100 points on the test. If we also assume that all of the questions are equally weighted (that is, some questions aren't worth more points than others) each correct question will be worth 100/35 points, or about 2.86 points.

That means that if a student answered 25 of the 35 questions correctly, she would have a score of 25 * 2.86, or 71.5%

Alternately, you could find a simple percentage by simply dividing the number of correct questions by the total number of questions. In our case, that would be 25/35, or .714, or 71.4%
