Honestly, if you’re a type of person who doesn’t try in school, who slacks off and doesn’t do homework then you are in no position to complain when you get a bad mark. What do you think? You don’t do your homework, you don’t listen to the teacher and you game/party when you should be studying. You think that’s going to get you a 100? No, it’s not. Sure you can be ‘naturally smart’ but if you’re so ‘naturally smart’ then you wouldn’t have bombed that test, now would you?
When people complain about doing bad in school when they don’t even try, it’s pathetic. You’re in no position to talk. Maybe if you actually tried a little then you wouldn’t be in this position.
