Misreported weighted GPA on common app by .03

I accidentally reported a weighted GPA as 4.06 instead of a 4.03. Is this a big problem? Should I contact the schools to change it? I’m applying to US selective schools.

It’s minor. No need to waste time contacting schools. For starters, they’ll look at your transcript anyway. Additionally, they’ll look at the UW GPA more than the weighted.
