This time of year I get many questions about when the different parts of the application need to be submitted. For instance, what happens if a recommendation letter gets sent before the application? As it happens, the answer is very simple.
It does not matter one bit the order in which colleges get different parts of your application. Once they get something that relates to you, whether an application, transcript, letter of recommendation, whatever, they will start a file for you. Every time they get something that relates to you they will put it into this file. Once they have all of the information needed, the file is marked as complete and it can be evaluated for admission.
Is there a “best” order to have things submitted? Nope. Doesn’t matter.
There are plenty of things to worry about in the application process, but the order of submission is not one of them.
