No, if the test is calibrated, marks are allocated to IQ figures according to how likely it is that the mark is scored. If the average mark is 56 questions right, then 56 becomes an IQ of 100. If 68% of people get between 51 and 61 then 51 becomes IQ 85 and 61 bcomes IQ 115 by definition. In a good IQ test it is very unlikely for anyone capable of taking the test to score zero without doing so deliberately. Probably it has never happened. Suppose the lowest score ever recorded was 10 and that happened once in 10000 tests. This would correspond to an IQ of 44. If you got less than 10, all you can say is that the IQ is less than 44. For this reason IQ cannot be accurately calculated for very low and very high scores. In theory IQ can even be negative. It would correspond to a test score so small it comes up in less than one in 76 billion tests.
