Need some advice on picking referees. I have two strong references from profs, but need some help with the third. I could approach a third prof who could (kindof) act as a character ref (I have never taken classes/research with him; just chatted during lunches and such). Alternately I could go with a volunteer co-ordinator I worked under. The problem is that while I've volunteered for a long time (3 years), the old co-ordinator left and I worked one summer with the new one, and this was two years ago. So I don't know how well she remembers me, but she's one of the only ones who could talk about the compassion/volunteerism side of things.
