2. Better grades are linked to having better education and more earnings. Having a higher GPA makes your annual adulthood earnings increase about 12 percent for men and 14 percent for women. People who have better grades are more likely to keep studying after high school. Better grades are also linked to a greater probability of going to graduate school and earning another advanced degree.
3. The correlation between high school grades and overall education attachment was strongest for minorities. Between minorities and whites with GPA's that were similar, minorities were more likely to go to college or extend their education after high school. This might be because minorities have to work harder for the things they get instead of getting it easier like whites, so they work harder to get where they want to be and to take advantage of education.
