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 the teacher is not using a curve, 33-7=26 so there are 26 questions right. The percent correct is 26/33 or 78.78787878 percent with the 78 in the decimal recurring, meaning this is a 78.8 or a 79, which is a C or a C+ in many grading systems.
71 percent
When I graded papers, no matter how many questions, I would mark the questions wrong that were wrong with checks. Then, to come up with a grade I would subtract the number possible with the number wrong. That would give me the total number right and from that you assign a grade to the paper.
10 - 3 = 7 7 / 10 = .7 = 70%
7 wrong out of 22 questions = 31.8% wrong. 15 correct out of 22 questions = 68.2% correct. I hope it wasn't a math test.
70% , which is a C. If you got 6 wrong, that means you got 14 right. 14/20 can simplify down to 7/10 (divide both the numerator and denominator by 7), and 7/10 is a 70%.
65% or D
You are in the C-D range. If you had missed 7 out of 15 that would be a solid D. You can do better I don't know you but I know you can do better.
no more than 7
70% of 25 is 17.5. That is you will pass with 7 (7.5) questions wrong.
Even if you assume the questions are all worth the same number of marks, the answer may well depend on the grade boundaries.
