Number of questions completed
= 94 - 8
= 86
Big difference
= 656 - 368
= 288
Small Difference
= 656 - 644
= 12
Number of wrong answers
= 288 ÷ 12
= 24
Number of wrong and incomplete answers
= 24 + 8
= 32
Number of correct answers
= 94 - 32
= 62
Number of more correct answers than wrong or incomplete answers
= 62 - 32
= 30
Answer(s): 30
