Number of questions completed
= 92 - 6
= 86
Big difference
= 504 - 304
= 200
Small Difference
= 504 - 496
= 8
Number of wrong answers
= 200 ÷ 8
= 25
Number of wrong and incomplete answers
= 25 + 6
= 31
Number of correct answers
= 92 - 31
= 61
Number of more correct answers than wrong or incomplete answers
= 61 - 31
= 30
Answer(s): 30
