If the school you go to offers this, you could pick 4 subjects, eg bio, chem, politics, and psychology, and then you can drop one, or if you make it in the bracket to switch, drop one and switch another. I don't think economics is the best subject for law, definitely for political sector, if i was you i would consider RE/RS, I do take it and if you would want to be a lawyer, you should definitely consider it. Hope that helps x
