Killed isn't the right word, but grades basically became a low priority. Because I've done the math, and they're unnecessary to be ultimately high for me, as long as they're decent, and the result will be be same.
Grades are important to me, but not moreso than free time. Everything in school just comes so easy to me, I get it within 1 or 2 times of having it told to me, then I become efficient very quickly with the skill and always finish homework at school. Unless it's a big project, I never ever have homework.
