Can a B bring up your grades if you have all A’s or will it bring your A down? (Please answer)

One B will bring your grades down if all you have is A's. Having an A means you got between 90-100% while a B means you got between 80-89%. So it depends on how much percent you got for B, for example, if you got an 80% and all you got a 95% as a grade, then your grade is going to decrease between two to eight percent depending on how your school rubric works.
