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.
To get seventy percent or better on a quiz of 16 questions one needs 11.2 answers correctly answered. So it is best not to miss 4 but definitely not to miss 5 or more. This answer is arrived at by taking the 16 questions and multiplying by .70 (70 percent) or 16 x .70 = 11.2.
0.70 x 125 = 88 questions right You can miss 125-88 = 37 questions to get 70 percent But you got to get all the rest correct!
