If I get a C in major prep class, will I still be able to transfer to UCLA?

I am an econ major who applied to UCLA. I might get a C in my major prep class in my final semester. Would they take away my offer then?

UCLA transfer decisions are not out yet so as not being admitted, you cannot look up their conditions of admission. However, usually they will rescind for D’s and F’s not 1 C. 2 or more C’s have to be disclosed to admissions. You should be fine if admitted but always verify once you are accepted.
