Number of questions completed
= 96 - 7
= 89
Big difference
= 513 - 297
= 216
Small Difference
= 513 - 504
= 9
Number of wrong answers
= 216 ÷ 9
= 24
Number of wrong and incomplete answers
= 24 + 7
= 31
Number of correct answers
= 96 - 31
= 65
Number of more correct answers than wrong or incomplete answers
= 65 - 31
= 34
Answer(s): 34
