Many of the schools that I'm looking into require at least 1 letter of recommendation from a non-science professor. It's been 6+ years since I've taken a non-science class, so I definitely can't ask any professors from undergrad. I plan on taking statistics this summer as part of my DIY post-bacc and hopefully I can get a letter from that professor. If the professor refuses, are medical schools more lenient on non-trad applicants LOR requirements? Is there any chance that if I call them, they may allow me to substitute the non-science professor letter with another letter from a science professor or a letter from a supervisor at work?
