Hi! Can someone help me with what I should do?

So I am a student in India in 12th grade, so ik it's late for me to start as a freshman but I am hoping to go to NYU in the junior year. Study 2 years in India then try to transfer to NYU. Ik this is also almost impossible but I can try right? And can someone also tell me what Extracurriculars should I build? Thank you and sorry for such dumb questions 😭
