Will my admission get revoked?

I’ve been admitted into UCLA but their admissions contract states that if my grade drops below a C, I must inform them right away. I have a D in AP Physics right now, and I am absolutely positive that it will go up before the year ends. HOWEVER, the contract says I need to inform them ASAP. Is that true?

the contract says you need to inform them of grades you receive, eg. at the end of a semester.
