Will this cause a college to rescind an acceptance?

I recently got accepted into Florida Atlantic University with a 3.1 GPA and a 23 ACT. I already committed to them and put down my tuition deposit. Last semester, I received all A’s and one C which was in precalculus. If I get a D in precalculus second semester but maintain good grades everywhere else, will this cause any problems?

It might. Try not to get a D.

Do everything possible to avoid a D as the year end grade. See the teacher after class, get a tutor, ask a friend for help, do extra practice problems, etc.
