Do you need a C in GCSE Maths if want to take Drama University?

No, you generally do not need a C (or a 4-5 under the new GCSE grading system) in GCSE Maths to study Drama at university. University entry requirements for Drama focus on subjects like English Language and Literature, and often require a portfolio or audition. Maths is rarely a specific requirement. However, always check the specific entry requirements for the *individual universities and courses* you are interested in, as there might be unusual exceptions.
