I have been accepted E.D to an ivy league uni to its art and science college.

Aside from lifting a lot which I intend to do I am interested in any ideas which would allow me to improve myself and game in college.

Where I am going to has a lot of fraternities should I join one or will I be arrested for some b.s frat situation?

I am also considering double majoring in economics and a science such as bio or maybe chem would these seem feasible majors to provide job opportunities later?
