Regarding LORs... is there any difference between the following, in terms of what programs would recieve in your application?:
1. Certifying and submitting today/tomorrow with 2 LORs assigned, and assigning the 3rd once the author uploads it on Monday or Tuesday (still before the 29th)
or
2. Waiting until the 3rd author uploads theirs on Monday and Tuesday, THEN certifying and submitting with all 3 letters at once?
I want to submit my application soon, but I'm worried that if I add the last official letter afterwards early next week, it won't be received as part of my original app
