Can an 8th grader apply to a college?

Yes, an 8th grader can *apply* to college, but it's extremely rare and highly unlikely they'd be accepted. Colleges generally require a high school diploma or equivalent (GED) for admission. While some exceptionally gifted students might be considered for early entrance programs, these are very competitive and require extraordinary academic achievements and maturity. Essentially, applying as an 8th grader is a long shot.
