When I was growing up, there was nothing better than bringing home a report card with good grades on it. I wasn’t a straight A student, but I got my share of A’s and B’s very few C’s. I guess I was what you call an excellent average student.
My parents were always checking my report card and questioned any low grades and encouraged me to do better when they felt that I was not working up to my abilities.
Since my education time up to today, good grades are still the benchmark we use to determine if a student is going to be promoted or retained. The higher achieving students, who are in high school usually strive for good grades in rigorous courses, because they know that their class ranking among other things will determine the type of college that they will be admitted to.
