<p>I've been out of school for 2 years and was planning to get 2 letters of rec from my supervisors and 1 from an undergrad professor (for the standard required 3 LoRs). But get this - one of the schools I'm applying for recommends that 2 LoRs be from professors. I called the school to double check and she said there is a bias for letters from people who have PhDs, and that I should find one more professor and send all 4 letters (she says they'll read them). Another school says they "require three LoRs from faculty members." Great. Now I'm scrambling to find 1 or 2 more professors for these specific institutions. </p>
<p>This forum and common sense always told me the better LoR comes from someone who knows you (an extra supervisor in my case) over a professor who doesn't. If I get 1 more LoR from another professor though, should I use their letter for just these 2 schools that require more professor letters. Or should I use him for all my schools, effectively sending 4 LoRs to every school?</p>
