UCSD admit here. I’m not a fan of the stats game. Frankly, I think it creates more misinformation and anxiety than anything. I think there is more range in these bare stats than most people recognize. But, since you ask, I’ll give you a basic description and try to keep it more or less holistic.
I graduated last May from a top private US university with a decent, not stellar GPA in soc and poli sci. Had a great Quant GRE score and just decent scores on the other two sections. I had done some research as an undergrad and wrote a thesis. Since I’m pursuing area studies in grad school, I’m sure it helped that I speak two other languages fluently. This year I’m studying relevant things abroad on a fellowship. My rec letters are difficult to gauge, but I imagine they were somewhere between solid and great and 2/3 were from prominent faculty.
These stats also got me into Wisco; and I think, had I submitted my bare numbers to this forum for review, they would have said that Wisco is a serious reach. But then again, this forum is full of crazy people (no offense, crazy people!).
Hope this helps and good luck to you!
