I've been in the same boat-it sucks I know but nobody can convict you with no evidence don't sweat it bro

If it's a university, some classes don't have any coursework. Your grade is based solely on exam performance.

This was the most idiotic thing I've ever read

Keep your fortune cookie self out of this please.

Ah, "society". That nebulous, faceless entity we all can use as a scapegoat cure-all for all our social, economic, sexual, political, physical, emotional, and mental ailments. And **** the haters, amirite? Having your "haters" doesn't mean you're doing something wrong, but it doesn't mean you're necessarily doing something right, either. It's just another weak excuse for acting like a pissy little child. After all, I as far as I'm concerned, you're just going to be another hater in the crowd because I'm calling you out on the Internet. See how that works? Hater!

to me, haters mean that i am doing something wrong, that they don't tell me about, and expect me to deal with it anyway. sometimes they hate for the past which they wont let go, and sometimes they hate me because i am different. to all of them, it means they hate me for something i did wrong in *their* opinion. key word: *their* opinion. i often meet people who don't care about it, or even support my policies, because its the right thing for me. that gives me the right to dismiss them as inconsequential. and, in my defense, the OP using society, so i used society as an example. I'm not wrong. society can be pretty damn bad, depending what you define society as. i just define it as the local area relevant to the situation. in this case, school teachers in that school.

WTF? So if you start out being bad at something, it's your fault if nobody believes that you've worked hard to improve? Dang, so if you fail an exam just drop out of school then, your life is over and never try to do better. OP didn't murder someone. They got bad grades. Then they got better grades. Any school worth their salt would have teachers who can tell that a student is working harder than they used to.

From the post it seems like OP is a more mature student, someone who's been at this particular school for at least a couple of years. So if this is the first time they've made an effort and actually worked hard, why wouldn't the teachers be surprised? One semester of hard work doesn't make up for a few years of slacking. It will take a little while for people to realise that OP is serious about doing well. You can't expect to do a behavioural 180 and expect people to just go with it. That's not how life works.
