Does coming to school early mean that you will have better grades?

So I have been wondering why so many students show up before the teachers. Most parents now and days have to show up to work before the sun starts. The work our parents do makes the students suffer because the students have to work more harder. The students who come early have the same opportunity as any other person. Being Earl to school somtimes does not mean that the person would not become a better student. It all comes down to what the person does with the studying.
