So, I have 4 recommendation letters and a committee letter. I want to use all of them because I feel like they will all be very strong. 2 are from professors I really got to know, sat in the front of class, went to office hours a lot. 1 is from my research professor I spent a whole summer with and have a publication with. 1 is from a doctor I went to Honduras with. Then the committee. Should I use less than this?
