Answer:
Mean
Step-by-step explanation:
The median gives you the middle score, but it does not give what you really want, the average grade that you have.
Mode is also valuable, but it only gives you which test score number you got most of, and gives no relations to more poorer or higher grades.
Mean is your best answer, for it takes all the answers and gives you the average grade by adding all numbers and dividing by the # of numbers there is.
