Common App Essay

Can I submit one essay for the main common app portion to one school and then completely change it for a different school that has a deadline a few weeks later? If so, can I do this an unlimited amount of times?

Can I also make changes to the rest of my application for different schools I am applying to? For example if I want to change my activities section or if I get another award in the near future?

Thanks!

Yes, you can do all of the above.

How do I go about doing that? And just to be clear, there is no limit on how many times I edit or change it correct?

Thanks!

There is no limit to changes PRIOR to submitting to any school. (but once you have submitted an app to a school, you can not change it and submit again to THAT school.)

Be very careful though. Personally, I don’t think you should need to make changes between every app. I don’t think colleges want to see an app that is carefully scripted just for them, as it is less likely to be a true picture of you, and more of what you think they want to see.
Be careful to keep yourself very organized if you plan to make a lot of changes. It is easy to miss a change you intended, and you might do more harm than good.
