Damn, why am I so stupid.

I find that reading helps to exercise the mind a lot. It gives you a better vocabulary, which could help you explain yourself better in a paper.
Instead of playing a videogame, try reading a difficult book for 20mins a night.

Reading never really has helped, because I actually read quite a bit and I don't really have much of a chance to play games anymore.

Btw I am in 11th grade, the year your grades really matter.
