I agree time and effort are very overrated in high school. I admit I cut a few corners at times, but mostly did the shit myself. Got high-honors most of the time and distinction a few times. But, I hardly put in any time into the work (projects I put a small amount). It's not because I didn't care, I just didn't need to put the time or effort. I never read a book, because I hate reading, and I never did my homework at home, but the point is...it got done. I took pride in getting such good grades with little effort...but all people are different, some need to focus more than others. There's nothing wrong with it, and I agree some people don't deserve the grades they get. But, I think I deserved my grades, because I found a better way to do things. Still stayed honest, just never stressed over things, and took more time to enjoy things rather than do work that you'll never use again.

But, don't get down man, karma will come around I'm sure of it.
