I have 2 letters of recommendation for Princeton from non-teachers (and 2 strong teacher letters). Both of the letters convey different aspects of my extracurricular life-- one relates to my work at an animal shelter and another relates to my work at a research program. However, I don’t want to overstuff my application, as I know for a fact my teacher recommendations are very strong. Do you think that it is worth submitting both optional letters or should I not risk diluting my application and only send one? Thanks!
