Self reporting scores when having a mix of test required and test optional schools?

I am applying to 6 schools. 4 I will be using as test optional (not sending test results) and 2 require test results.

What should I do in the common app in terms of self reporting? Can I leave this section blank since I will be sending the scores directly to the two schools that require it?

I am concerned about listing test scores for schools that I don’t want to see them.

Any advice is appreciated!

You are not required to report test scores on the common app.

You can absolutely leave it blank.
But you can also handle it differently for different schools if you want. You can make changes between submissions if you’d like to report some scores to some schools and not to others.
