Like Gluffalo, I submitted all requests for eLORs the day VMCAS opened (first week of June). That being said, I had asked all of my writers if they'd be willing to write solid letters of support for me well before this date. I had letters submitted from clinicians (human and veterinary), faculty, and industry scientists (5 total). Of these 5, 3 of them submitted the final week of the deadline. I highly recommend requesting your eLORS electronically as soon as the application opens (officially register your supporters in the VMCAS system). As the deadline for submission draws near, gently remind these individuals that the date is approaching. I reminded my writers at 1 month intervals, followed by two week and one week intervals in October (the month of submission). Good luck!
