Set up the ratio in this form:
(number of correct answers / total number of questions) x 100
Since there are 42 questions total in a test, we have:
(number of correct answers / 42) x 100
Whatever number of correct answers the student has on a test, you compute the grade for him/her. For instance, if you have all correct answers, then we have:
42/42 x 100 = 100%
