okay okay

I need some answers

we took a test the other day in geometry honors

and only three people got As

as far as I know, no one got any Bs

so everyone either passed it, or failed it. there is no in between

I got a 71, a classmate got a 60, a friend got a 57. a kid in my grade who got a 26 on his ACT as an eighth grader even got a 71

nearly everyone in that class has a C average while passing with flying colors in every other class

another point I have to make is that he handed out four different tests. in other words, he made four different tests with similar questions and passed them out randomly.

so based off of all of this information, this is my question:

is the fact that the majority of the class failed a problem with the students, or a problem with the teacher?
