a student's 10 scores on 10point class quizzes include a 6, a7, a4, five 9s, an 8, and a 10. The student claims that her average grade on quizze is 9 because most of her scores are 9s.

Nope.
Find the mean or the average by adding all the scores and dividing by 10.

9 is both the mode and the median.
