Transferring with a W

I know this kind of thing is asked rather consistently but after searching through several threads I couldnt really find a comparable situation to the situation Im currently in.

I currently have the TAG to UC Davis from a California Junior College and that got approved back in November. I am currently above the 3.3 GPA requirement for my Engineering agreement but not by too much (3.36). Theres a class I’m having issues with right now, and it is part of the prerequisite classes for my major. That said, I still have time to withdraw from the class and at this point, probably think its best to do so. I have never withdrawn from a class before.

With the guarantee that I will be accepted to Davis (from what Im hearing it will probably be on Friday), what would the odds be of having my transfer offer revoked when I submit the W after I have been accepted?

Honestly the best thing would be to contact someone from Davis and ask them about your situation.
