Ok, so I know that most of LS admissions are best on LSAT scores and GPA, and I know that doing ECs "can't hurt" in the application process, but can doing an activity like debate or mock trial uniquely increase chances of admission? I've spent a couple years involved in collegiate debate, which requires extensive research and skills of argumentation, communication, and analysis. I've enjoyed it, but if law schools don't notice its relevancy, there are other ways I can spend my time. I did mock trial in high school, and the school I've just transferred to is home to the defending national champions of the collegiate circuit. Is this incentive enough to commit to mock trial? Would either activity stand out more than others in the application process?
I'd like to evaluate this purely on the basis of competitiveness. I understand the importance of the "college experience" and staying true to my interests, but I would truthfully be just as happy doing mock trial, debate, or spending my time pursuing other things. I'm majoring in poli sci, minoring in public policy, planning on spending a quarter in DC, and committed to undergraduate research to renew a scholarship. With these things in mind, what would you recommend?
