Will UCLA rescind me if I W/Drop my Calc BC class?

-I risk a C maybe D if I continue
-I am Halfway through the semester
-However, I Am taking the course at another school where I can get an A or B that will go onto my transcript for Calc BC, but will still have a W.

Does anyone, have any experience with getting a W and possibly still being accepted? Or does anyone have an Idea of what UCLA may do? This is a big decision right now for me as to whether I should drop it or not, so help would be Much, much appreciated. Thanks

Contact UCLA admissions before dropping the class

their policy is not to comment on that so thats why
