Are these good A level choices?

I have currently chosen politics,economics and history for A level. I love all these subjects and I am looking forward to doing them but am I missing another hard a level and will these options be attractive to universities or do I need something else.

Do you know what you want to study at university?

You are only required to do 3 A-levels, doing 4 could put you at a disadvantage if you don't do well in all four.

I am considering politics but I am afraid there are very few jobs in that field. I am also considering a economics degree but I am afraid I will need a level maths.
