The Letter of Recommendation part I got from last year stated:
"Letter of Recommendation. Letters must come directly to our office. Use the address listed below. Indicate the type of letters we should expect from you:
Pre Profesional/Health Science committee letter or packet
Medical experience letter will be included
Will sent separately
OR
Separate letters from two science professors.
Separate letter medical experience letter."
You would then check which one they expect from you....
If you have access to a committee file, then do so.... In my committee file I had, I think, 12 letters of rec, so it was much more than what they've asked for, but it did include that all important committee letter.
My best advice is to get a hold of Barbara Fox or Becky Grissom. They are very helpful. If they're not there, just leave a message and they will get back to you.
Good luck to you....
