What happens if I change my personal statement on Common App?

I’ve already submitted my application to one school via Common App. Right now I have two possible personal statements, and I’m thinking I might switch it up based on the college that I’m applying to. So, I just wanted to confirm - if I change the personal statement, that doesn’t affect the ones I’ve already submitted, right? (I could theoretically just go back and forth in between submissions?)

Yes, you can make any changes you want, including your essay, but it/they will only be seen by colleges you apply to in the future.
