Number of questions completed
= 92 - 7
= 85
Big difference
= 404 - 252
= 152
Small Difference
= 404 - 396

Number of wrong answers
= 152 ÷ 8
= 19
Number of wrong and incomplete answers
= 19 + 7
= 26
Number of correct answers
= 92 - 26
= 66
Number of less wrong or incomplete answers than correct answers
= 66 - 26
= 40
Answer(s): 40
