What are my chances at Cornell University?

I have a GPA of around 3-3.3 with an 85%.
My current SAT score is 1140, but I have taken another and am thinking it would be near 1200.
I have taken AP Physics class, did well in class got 90% on most test. However, on the exam I got an 1. I’m really not sure what went wrong, but I am kind of suspecting that maybe it was because I had used a mechanical pencil for the multiple choice… I don’t think I should be sending this poor AP score.

you have really limited chances based on your GPA and test score
