Final answer:
After submitting your Common App to a school, you cannot edit it, but you can make changes before submitting it to any school.
Step-by-step explanation:
Unfortunately, after you submit your Common App to a school, you cannot make any changes to it.
However, there is an exception to this rule. If you have not yet submitted your Common App to any school, you can still make changes to it. Once you submit your application to one school, it becomes final and cannot be edited.
It's important to thoroughly review your Common App before hitting the submit button to ensure all information is accurate and complete.
