UC Davis Rescind?

I got an acceptance and am eager to attend UC Davis from the fall.
My grades are above a C and my GPA is over the non-resident minimum requirement for the UC system.

HOWEVER, I keep getting anxious from what my IB score could be. If I severely under-perform in the IB exams, will that be grounds for UC Davis to rescind their offer, although it’s not explicitly written on their website? I don’t think I would fail the IB Diploma in all but the thought it self is very frightening.

ANY opinions or first hand experience would really help me out in calming me down.
Thanks!

You will not be rescinded for lower than expected IB scores but you may not get course credit if you do not get at least a 5.
