Does Facebook effect what grades you get in school or college? That's a question which a lot of people think the answer to is yes. However a recent study shows that it's not Facebook itself but how you use it. Obviously the more you revolve your life around something, the less you're going to concentrate on other things, the same applies to Facebook. The average time an average student spends on Facebook is around 106 minutes per day however, the more you spend the more your grades will be effected.
