I personally connect with this one pretty well, as a person who has gone to school at one time or another, and has been expected to get good grades because of intelligence, I have always despised it when either: someone expects you to get good grades because you are smart (as previously mentioned) or when someone talks down to you because your grades are bad. I think many people have old-fashioned ideas about school, because I can tell you from experience, grades rarely have anything to do with intelligence.
Sorry about that, my spiel aside, great work, I really like the Canterlot High series.
Bic Mac isn't stupid! he's smart! it's like artists! They have amazing ideas but they can't it from their minds onto paper! So maybe Big mac did do his homework he just doesn't know how to put it on his papers.
I disagree with the general consensus that big Mac is stupid. Just because he doesn't say much doesn't mean that he's not intelligent. There are people that believe that if you're going to say something it needs to be something worthwhile.
the person mention in the description that the F aren't because he's stupid, but he because he has so much work on the farm it gets in the way of finishing his homework and studying. doesn't matter how smart you are if you have no time to work on it
