Will Chicago rescind its offer if a student get a C in the 2nd semester?

My son got accepted by Chicago. He had never got a C in his life but he has a C now. Will the school rescind its offer if he ends up with a C on his transcript? Should I worry?

No. As long as it is not a D and he commits no felonies, he’s fine.

No. I got a C- and my overall GPA slid by around 0.5 in my 2nd semester of senior year, and I’m at UChicago right now.
