I would like to set up a course as follows: Three equally weighted exams will count 75% of the final grade. Ten quizzes which make up the remainder 25% of the final grade. I would like to set it up so that if the average of the three exams is less than 70%, then the final grade will be only the average of the three exams. If the average of the three exams is greater than 70% then the three exams plus the quizzes will make up the final grade.
Appreciate any help!
