what do i need ,to go to Harvard?

Correct sentence structure which you obviously don’t have.

Plus $$ and connections.

Go to or write the Harvard Admissions office with specific questions and information you need. Ask them specifically about requirements: What is the GPA range requirement for entrance? What are the over-all requirements? If you are currently attending another University or expect to before transferring to Harvard, find out what courses in your degree plan will transfer. HEADS UP PLEASE: Just because there are specific courses that must be taken for a degree requirement, even if the course catalog was written 6 months to 1 year ago, curriculum requirements change so quickly the printed material, to some degree, can be obsolete. BE CAREFUL!

Big brains. And no social life.
