@david.busis Could you expand on why adcoms have dinged applicants for sending a third letter? I had planned on sending two academic letters and a work letter, so I'm just curious. Thanks!
I read that to mean published scholarship or like a presentation at an academic conference or something. I can't imagine Columbia wants to know about my final paper from ENG 343, or my class presentation on Homi Bhabha.
That's true, though some schools ask/require LORs from work if you've been away for 2+ years. So while you should probably only use academic LORs for most schools, you'll need the work one for a few others.
