3 A levels and 1 AS or 3 with an EPQ

The 4 A levels I'm doing are maths, Further maths, physics and economics but I will only do economics as an AS. I havent started economics as they are still sorting out time table issues but it should start next week or the week after currently I'm in business until economics is set up which I find boring and hate it.

I'm not sure if I should just do maths, Further maths, physics and an EPQ on a maths related topic.

I want to go to uni and study maths as it is my favorite subject. Could you just share your opinion on what I should do.

Also I'm quite good at researching I think as in my GCSE I got an A* for the research coursework in Computer Science.
