What GPA do you have to get in middle school go Harvard?

There's no specific middle school GPA requirement for Harvard or any other top university. Colleges look at your entire high school academic record, not your middle school grades. While a strong academic record throughout middle school is beneficial for setting you up for success in high school, it doesn't directly influence college admissions. High school grades, standardized test scores (SAT/ACT), extracurricular activities, essays, letters of recommendation, and other factors are far more important in the college application process.
