I am planning on not going to school for a bit probably a year or two, but would like to get couple of recommendation letters from my science professors so I can get that sorted away and before they forget me lol. I was wondering if the lor can be electronic and sent to me, and when I plan to apply I can simply change the date of the letter? Can the letter be open ended or does it have to be towards a specific school? I am not too familiar with the LOR process, but i am assuming they will send it on pdf or microsoft word format with their signature and when I apply towards dental school I will send it directly to the schools im applying to?
