Will universities accept maths and further maths as two?

I'm currently taking maths, further maths, physics and politics for A-Level and am being pressured quite a lot by the workload. I want to take maths or maths and philosophy at university, so thought dropping politics would be the best decision. Will this impact my opportunities at being accepted into university, as I've heard some universities consider maths and further maths as a singular A-Level.

This varies by uni (and potentially by course). Which unis are you considering?

Oxford, Durham, Warwick, York and Hull (fallback uni).
