2×(4+ 1)= 10 (minutes)

90+ 10= 100 (integral)

Answer: Math score 100.

Solution: First, the average score of math scores after adding up is 92. The average score after adding up the math scores is higher than that after excluding the math scores, which means that the math scores are higher than others. We can confirm that. Then 92-90 is the extra copies of the average score after the math scores are added up, and one * * * gives five courses points, which is ×5, and the subjects whose math scores do not include math scores are 10 points. 10 plus 90 points equals 100 points.
