You have a lot of choice. You can even go into medicine/biology without biology a level as chemistry is the only "required" a level for that.
Economics at uni requires maths, which you've got!
With those a levels at A/B grades you would also be an excellent candidate for psychology degree, since you need to be able to both write essays and do stats!
You can do everything (grades permitting) EXCEPT Engineering (but you may be able to do Chemical Engineering at some unis), Physics, English, History (you may still be able to do History at some unis) and Biology (you will still be able to do it at some unis).
