When Do Colleges Rescind Acceptances?

@Sally_Rubenstone RIght now, in my classes I expect to have at least one C in My AP Computer Science course. This isn’t going to be used in my major and I’m expected to have an A as my final grade in that class as well. The only other grade I think may slip is AP Macro, which is dropping from a low A to a mid B, which may drop that final grade to a B. I’m a bit worried that Lehigh will rescind my acceptance. Do you think I will get a rescind or a warning? Thank you for all the help you’ve done on this thread throughout the years!
