Probability of getting rescinded?

I got accepted into UCI for the Fall 2017 semester under a Public Health Sciences major. I have a cumulative GPA in good standing, and even with the grades I’m getting this semester I am likely to stay in good standing. However, one of the classes I’m taking - 3rd semester Calculus - there is a possibility I will get a D in the class. If it is not one of the prerequisites for my transfer, what is the possibility that I can get my admission revoked? I am very concerned about it right now.

Did you ever got a answer to your concern? I want to know as well. Thank you.
