Can you still get into an Ivy League school if you have a low SAT score but high IB points?

Ask again when you have actual scores, but no, you have basically no shot with a 1200, not even as an internationally ranked recruited athlete.

That said, there are plenty of schools that would love a student with those stats. But again, let’s wait until you have actual scores.

And, as an aside, your predicted IB score will not matter, but good luck with that as well.
