I may intend on doing a double degree when I enter the university in the future. But I wonder is it really very difficult. The few reasons as to why I want to do a double degree is because that my interest lie in both physics as well as the human sciences, and sometimes I feel "incomplete" if I just focus on one at any one time. I am thinking of a degree in physics, as well as sociology. But is it going to be difficult as these are fields which are somewhat unrelated. Has any of you done it before?
