What do i do?

I really want to go to an ivy league. As much as everyone says, “it isn’t worth it”, “you won’t get in” ect. It’s always been a dream, but a dream coming with hard work. But i feel like i’m so behind. I take algebra 1 honors and physical science honors and i feel like i’m so behind. there’s freshman taking algebra 2 and chemistry. idk how i can catch up, or even make it to an ivy is there any way i can with the classes i have. i really need the advice..

Please.
