Course Choice

I'm off to do EEE but am trying to consider what 'other' subject to take alongside it. I know that the first year or two of my course are fairly generic with general engineering topics covered.

I'm thinking of either taking maths or physics alongside it, my preference would be for physics, any opinions? I regret choosing this in part now since maybe I should've gone for a maths with physics or similar course! Thankfully Edinburgh's flexible so I could well end up with a physics degree, I'm not sure if anyone else has thought about what other subject to take on (assuming the same flexibility applies across the uni).
