Consider a paid service like Interfolio. Your professors write the letters now, Interfolio saves them for however many years and sends them to AMCAS when you're ready. Very popular for premeds.Thanks guys, another thing I'm slightly concerned about is acquiring letters of rec. UK doesn't have a pre-med committee to my knowledge so no need to get a committee letter but that means I need to get 3 letters from profs, which seems a little difficult considering I'll have been out 2 years by the time Im asking for a letter. I did have my Community Nutrition prof (also my undergrad advisor) write me a letter for PA school, I doubt she would care to write one for med school, so that would cover non-science. Of course I could also buddy up with whatever prof I get for physics this spring from my local community college, so that would be one science prof. But that does leave me one science prof short, should I crapshoot email science profs from undergrad, hoping they'll remember me?
