Will I get rescinded?

I recently just got accepted into IU and I am very excited! Freshman year I got a D in Algebra and a D in Earth Science. In my college essay, I wrote about how math is very challenging for me and how I am trying to overcome it. Sophomore and junior year I got C’s in my math classes. Well now I am in Stats and it is a very hard class. I’m almost sure I will get a D in it. But All my other classes are A’s and B’s and I am in 2 honors classes at the moment and will also be enrolled in an AP class next semester. With my previous math grades and they knowledge they have about my issues with math how much will they care? Will they take back my admission?
