Grading Scale

I got my grades! Normally, this is an extremely happy occasion. And I am happy. I still have an excellent GPA, it's exactly where I want it to be. But a little part of me is nagging about a couple grades that are lower than I expected without me really knowing why and the fact that people I know who don't put nearly as much effort into their grades get similar grades. Now I know this is part of life. There will always be people who put in less effort and reap the same rewards. You just hope karma kicks them in the butt. And I keep preaching that "you can't compare your successes to anyone else's" so maybe I should follow my own advice.
