all great grades do it win you some free college money, and even then if you are lucky.
stuffty grades can still get college pretty easily lol, just gotta take loans the usual way.
That's the thing. Sure you can get into college with bad grades, but since usually the ones with good grades are hard workers and most likely do things outside of school (Volunteer, etc.), they have a much better chance at getting into a university with possibly even all of it paid for.
Basically, why get a C when you can get an A, because even if you might end up doing the same thing in the future, not everyone's life works out like that lol.
Plus with higher degrees you have more job possibilities than someone who doesn't have a college degree. (Doctor, Dentist, Surgeon, etc.)
I get all A's, but that's because I don't see the point in going to school 5/7 days of the week just to give half effort lol.
