Professional (pre-health, pre-med, business) Fraternities at UCSD

Hi everyone,
I’m going to be transferring to UCSD for Fall 2019 as a molecular and cell bio major. I know it is going to be tough to make new friends, and I’m actually going towards the pre-health (maybe pre-med) route, so I wasn’t sure if I should join those pre-health frats, like Delta Epsilon Mu. I was leaning towards joining a sorority, but seeing the drama my sisters went through, and the cost, made me not want to do one since the dues are more expensive at a UC. Is it beneficial to be in those pre-health/pre-med frats? Would it be in the way of my school work? I know I would have to definitely prioritize my time, but I just want to know if it is worth it in the end. Also, do they haze? Thanks in advance!
