You can't get exactly 70 percent, because that would be 11.1 questions wrong out of 37. If you miss 11 or fewer questions your score will be above 70%; if you miss 12 or more questions your score will be below 70%. This assumes the test is more or less "straight"; if it's scored like, say, the SAT (where leaving a question blank does not reduce your score by as much as answering incorrectly) then we'd need to know the exact details of how the test is scored.
