Question on getting rescinded?

Hello, I recently got accepted into CAL as a Fall 2018 transfer admit. The thing is I’m failing one of the classes that I listed that I would take because I decided to overload myself with 19 units of STEM classes this semester. I might be getting a D in the class. The class is not a major prerequisite and not even one of the recommended class for my major. It is not an iGETC class, but just an extracurricular class I decided to take. Even if I get a D in the class, I believe my cumulative gpa would still be above the 3.0 requirement.

I noticed that the admission contract requires that I need to get all C’s or better.The drop deadline has passed last week. Berkeley has been my dream school, but now I think I screwed myself over by taking this class. Would I be rescinded if I potentially fail the class? I noticed that Berkeley is offering the class in their summer session, has anyone heard of any chance where admissions let people retake classes in the summer?

Fill out the update form/contact admissions, it is unlikely they will rescind.

I shall fill out the forms once I get my unofficial transcripts. I’m really anxious right now , I really hope they don’t rescind me. Thanks for replying.
