What a-levels should I take if I want to study law at Cambridge?

I am currently in year 10 but I am looking ahead and I would like to be clearer as to what I want to study for a-levels. I am set to get sufficient GCSE grades to apply for Cambridge so this is not a problem. I feel very secure with my choice to study law at Cambridge, and I wanted some advice. At my school, you HAVE to study 4 a-levels, with the option of doing an EPQ on top of this.

My GCSES (12 of them):
. English Literature
. English Language
. Biology
. Chemistry
. Physics
. Maths
. Further Maths
. Computer Science
. Geography
. DT
. RS
. German

I have whittled the a-levels that my school offers down to 6 choices (based on subjects that I am good at or interested in):
. Economics
. English Literature (although I don't seem too keen on this)
. Philosophy
. Maths
. Politics
. Geography
. Possibly an EPQ? (would likely be law-based)

Out of those 6, what 4 would best set me up for a law degree? Would doing a science or any other a-levels be more helpful? Would doing an EPQ on top of this be worth it due to the additional workload?

Any combination of those would be fine. You only need 3 A levels for Cam, so either pick 4, or 3 plus an EPQ. What is most important in the grades, so minimum number and the subjects you think you can get the best grades in.
