I agree, in fact, it only increases fear and anxiety which happened to me. Someone else could get an F on a test and they may be disappointed, and their parents may be as well, but I would be extremely worried and preoccupied about how my dad would react. Like, will he get so mad that he will hit me? Will he lose control and say or do something else he'll regret? All questions I asked myself if I ever got anything between an F and a C. And yeah, bad grades can be from anything.

I've gotten bad grades not because I didn't understand the assignment, but due to the fact that the teacher was consistently not clear about what she wanted. It can even be due to personal opinion towards someone. I've seen that happen where someone will do a great job on something and will get an A and someone else who does just as well gets a B or C. Or even if someone makes some mistakes, a teacher may be more forgiving towards some students compared to others. That's why I don't believe grades always represent intelligence 100 percent of the time.
