Typos in my common app activities list

Applying to College Common and Coalition Application
1

I found a couple typos in my activities descriptions after I submitted my application. It is the only part that I didn’t check carefully. Is it really a big deal? What should I do to make it up?

2

Nothing.

3

Ageed. Do nothing. It’s not a big deal.

4

Don’t worry. Give yourself a break and don’t look over the CA anymore.
