Few relationships starting out at this age were meant to last. Some do, most don't.
And if all your concerned about is that she's got a nice ass, nice boobs and a nice figure, go drown yourself.
1) She's out of a fucking league. If she's really what you describe, get a mirror. Stare at it. For hours.
2) It probably won't work out, looks isn't all that counts in a r/s.
3) Hotties like her aren't usually keen on having a steady partner, most of them just play with you and throw you away.
4) It's gonna fuck up your studies either way.
