Number of questions completed
= 98 - 4
= 94
Big difference
= 552 - 399
= 153
Small Difference
= 552 - 543
= 9
Number of wrong answers
= 153 ÷ 9
= 17
Number of wrong and incomplete answers
= 17 + 4
= 21
Number of correct answers
= 98 - 21
= 77
Number of more correct answers than wrong or incomplete answers
= 77 - 21
= 56
