OK, now this might be a stupid question but I'll ask anyways. For those SDNers who did a masters did you guys get LOR from faculty in your masters program or did you go back and get Profs from your undergrad to write them? Are the Profs in the masters program willing to write reference letters? Or do I still need to keep in touch with my undergrad porfs? Also do D-schools differentiate between the LOR or prefer one or the other? I am looking into non-thesis masters and any help would be greatly appreciated Thanks a lot!!
