Hey guys! I have 5 LORs in the pipeline for this cycle. Most of my programs require/only consider 3 of them, and I know which 3 should be the strongest. I want to know what I can do to ensure they read the strongest ones. How do they select which letters to read? Is it the adcom’s preference? First 3 submitted or requested?
Any insight would be greatly appreciated!
