Assuming your class is based on a normal 100 point scale, if you got 4 questions wrong out of 20, your grade would be an 80% or a B-. To find the point value of each question, divide 100 by 20. You would get 5. If you missed 4 questions, that would be a total of 20 points missed, which would leave you with an 80% out of 100%.
