Hey I can offer some insight on SPHSP. My friend did it in 2013. She had no research or any summer internship experiences. She did have a stellar GPA, good/excellent LORs and I believe her writing was on point too. The min. GPA is 2.7, so I think that's preeeetty forgiving. I don't think it's THAT competitive. (I'm only basing my opinion on what she's told me). There were NO FRESHMAN OR SOPHOMORES during her program!! They seem to prefer juniors and seniors and recent graduates.
Thanks. Do you have any idea when she found it? Also, was she an URM? I fall into the ORM category so I was wondering if that would detrimentally affect me.
