About scholarships please help?

To get a scholarship in colleges/ universities do they count your elementary education? Do they look at your grade as a whole or at your assigments? With a 3.7 gpa - 3.8 gpa will i be able to get a scholarship? Let's say you get a detention or something like that will that affect you? If you get an F or D will that affect you also as an assigment not as a whole grade?
