For example, can if I ask for a LOR this year and keep it on file on pharmcas till the year? The reason I ask is because I'm currently working at a lab as a lab intern and I basically work directly under a scientist and I think she may be able to write me a good letter of rec. However, it's a special program where I can work until May and then I'm done, but I'm only a second year and wont apply to pharm school till fall 2008.
