Major Prerequisite and TAG

Hello,

I have submitted my TAG application to UC Riverside, and I listed Chemistry 1B as in progress as I am currently taking it. Though I was wondering, if I were to drop it would it affect my TAG submission? As there is a very fine line of me not passing, due to the fact in which my professor does not curve even though the class average in tests is 50%. Because of this I am not sure if I will be able to pass but do not want to jeopardize my TAG application. I looked on TAG and Assist and my TAG requirements are fulfilled but my Major Requirements are not (Biology). I need to pass this Chem in order to fulfill my requirements. Though I was wondering if it would be okay to drop it and take it next semester, or if not as I had already put it as in progress for this semester.

Thank You.
