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.

Assuming that you get all your answers correct (can you rely on that?), you can miss 12.
To achieve a score of 70% on a test of 125 questions, you would need to answer 87.5 questions correctly (125 questions x 70% = 87.5 questions). Since you can't answer half of a question, you would need to round up to 88 questions. Therefore, you can miss 37 questions (125 total questions - 88 questions answered correctly = 37 questions missed) and still achieve a score of 70%.
