Should I drop a level further maths?Watch
Well, I'd suggest keeping both because doing FP2 and FP3 will make your calculus, graph sketching ability, vectors, coordinate geometry very strong. C3 and C4 become really easy afterwards. What modules did you do and what were your final UMS, if you don't mind me asking?
Oh, I'm sorry mate, I thought you were in A2 for some reason. I'd suggest keeping further maths to at least AS - it's of very high value to universities. C1 is really the foundation of A-level Maths, considered by many to be the easiest maths module. Have you tried going over the content in www.examsolutions.net and practising some book questions? If you keep doing so, you'll get a hang of it. What other modules are you doing?
This year, you'll be introduced to plenty of different kinds of maths - they won't be difficult, but you'll meet many new concepts. In order to do well you'll need to do a lot of practice - give at least an hour a day to both maths and further maths outside school right now. Honestly, it's really not too difficult to get an A in both, you'll just need to devout time to study independently. I'd say go for it and don't think of dropping AS Further Maths, it's highly regarded by universities (you might even want to continue to A2 by the end of the year!)
