What grades you submit to a college depends on when you are applying. Generally with early action, you’ll be submitting grades from your junior year, since you will be applying in the fall semester of your senior year and won’t have a full semester of grades from senior year to submit. If your grades from junior year are not as good as you’d like them to be, consider applying to regular decisions and spending your senior year picking your grades up. There’s nothing wrong with waiting a little longer to submit a stronger application.
