Don’t take the ACT. It’s a waste of time and doesn’t look any better than just having the SAT alone. You have the numbers BUT you have to know that with the size of Harvard’s applicant pool you should find a way to stand out. Some story, some talent, something that you’re passionate about. Is it crochet? Is it building websites? Painting? The Ivies get thousands of applicants every year who are president of x amount of clubs and have a 4.0/2400.
