<p>Let's say that you're applying EA/ED to a school or two by November 15th. I know that you can't edit your main common application when you send in your first application. However, can you work on other schools supplements after you turn in your first application?</p>
<p>For example:</p>
<p>I'm applying EA/ED to College A. I need to turn this application in by November 15th. After I submit that application, can I work on the supplements to Universities B and C that won't be due for a while?</p>
<p>I /think/ that’s how it works. You can send supplements in without the rest of the application so I assume it works the other way around too? Sorry, that isn’t much help. I could do with knowing the answer myself!</p>
<p>Okay this might help! (Copy and pasted from the Common App FAQ)</p>
<p>"HOW DO I SUBMIT MY COMMON APPLICATION?
Once you have answered all required questions, you may submit your application. Click the ‘Submit’ button to submit your application - - this button can be found on the ‘Sign & Submit’ section and the ‘My Colleges’ section.</p>
<p>You must submit the Common App to each of your selected institutions. This can be done all at one time, or one at a time. After you have submitted your Common App, you may add additional institutions and submit your application to them, as well. Once you have submitted your Common App to any institution, your application will be locked and you will not be able to make any changes to it. "</p>
<p>"MUST THE SUPPLEMENTS BE SUBMITTED AT THE SAME TIME AS THE COMMON APPLICATION?
Some institutions require that you submit your supplement before you may submit your Common Application; this information is provided for each institution in your My Colleges list in the ‘Future Plans’ section of the Common App Online. Additionally, if you submit your application electronically, you MUST submit your supplement electronically as well (it cannot be printed and mailed). "</p>
