Chances?

I have a 4.0 GPA UW (#2 in my class)
1220 on SAT
Volunteered as an EMT, shadowed a doctor, had two jobs during the course of high school
Letter of recommendation from my chem teacher who loved me, so I think she wrote really good things
Applied for Harpur, Psychology/Pre-Med

Your SAT is a bit low, but you should still have a shot at being admitted since you’re applying to Harpur. I would use Naviance to determine where you lie in terms of SAT/ACT score and GPA (I dont know if your school uses Naviance). According to Naviance and the Bing website, the average SAT score there is a 1360.
