Hi I'm quite new to this, but here I go. I am 23 years old and I have been out of undergrad for about 2 years now. What are the specifications for the letter of recommendations (how many and by whom). I understand that some are required to be from science professors, but being out of school I haven't had any face time with professors for some years and feel that these letters wouldn't be current. Right now I work for a biotech firm where I can get 2 LOR from my manager and supervisor (but would that be redundant). It is also difficult to get alot of shadowing experience because I am working full-time. I have shadowed a dentist about a year ago, but only for a short time. I would really like to apply this cylce (my DAT is already 1.5yrs old - pretty good score but never applied). But I'm so ill prepared and I really don't want to apply twice if I don't prepare well enough for this first time. Thanks in advance for your responses.
