Your score would be 90.91%
22 questions can be wrong. This means that you would have to get 33 marks, which is 60%
81.818% Solution: 81818 = 1-(6/33)
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.
33 ÷ 35 = .94 (rounded off) To change a decimal to percentage, move decimal point 2 steps to the right. So .94 = 94 %
In order to score 78% correct on a test with 150 questions, assuming that every one of the 150 answers is given equal weight, you must answer exactly 33 questions incorrectly. No more, no less.
85% - wrong. The answer is 33% See beliefnet
To score 65% you would need to answer 32.5 questions correctly. As you can't answer half a question correctly, you will need to answer 33 correctly resulting in a mark of 66%. Thus you can miss 17.
