Does economics degree have C4?

Im not sure why you think I would know anything about this?...

Please I want to know now if it has c4 so I can edit my cv before results day

I imagine any calculus may be used (although economics skews towards differentiation methods rather than integration as I understand), along with any basic algebra and functions material. The bimonial theorem and sequences/series will probably be quite relevant for stats and probability elements (and if you end up broaching some proper analysis content, in the more mathematical courses). Although I highly doubt you'll use vectors in an economics course, it's quite likely you'll learn about matrices (possibly going into linear algebra territory for more mathematical courses such as Warwick and LSE) which are related.

I'd assume you would be doing lots of maths, especially for economectrics at a level beyond c4 and A level, at least that's what I've been told about my uni. Linear Algebra (so vector spaces matrices etc.) , statistical inference (probability distributions, Hypothesis testing, estimators, stochastic processes) and calculus are the main areas, but don't worry it will be taught and you may be able to avoid some of it in later years because of module choices.
