HELP! Mistake on Common App Self Reporting Scores

On my Common App, I self reported my ACT scores but for my writing section, I put the date as 10/22/2016 when it would be 2015. Is this a huge deal? I already applied to 4 schools with this error. Should I email or is it not a big deal? I sent the official test scores to each school…

No big deal. I would not worry about it; it’s a very small error, and not worth the energy contacting colleges to correct.
