Looks like you lucked out! My sister had a professor one time that told her to just WRITE her own recommendation and he will just sign it! So she wrote what she wanted and he signed it. It worked for her.
There is a box on the LOR that states if you want the right to be able to read it or not...or something like that. Reading your LOR's isn't against the rules, but a LOR that you waive all rights to view is much stronger than one that you have viewed.
At 2 interviews this cycle the interviewer asked me directly if I had read any of my LOR's.
The dentist I shadowed for a long time wrote my LOR. However, he sent me his stationary so that if I didn't like it I could write it myself. He gave me his permission to use his signature or anything I needed. Is this wrong or am I just getting hooked up?
