I did exactly those 4 subjects for AS (plus the EPQ) and this year I'm planning on dropping economics.
Like Numero Uno said you have time to decide what you want to basically do with your life but if you're not sure then these combinations may work in your favour just because you'd have a selection of hard sciences and a soft science. Maths would go really well with all these subjects and allows you to have a bit of flexibility between your choices for courses at uni but at the end of the day if you're unsure about what you want to do in the future just pick subjects you think you'll enjoy
