30% or F
That's about 78% correct ... probably average grade, perhaps a C.
To calculate the grade, first determine the number of correct answers. If 50 questions were answered and 7 were wrong, then 50 - 7 = 43 questions were correct. The grade can be calculated as (43 correct / 50 total) x 100, which equals 86%. Therefore, the grade is 86%.
If you missed 12, then you got 31 correct [43-12=31]. If all questions are weighted equally, then 31/43 = 0.721 or 72.1 %, so your grade is 72.
