SAT Registration questions 2022

Yes, I have not gotten very far in this process!
My son has autism, and wants to go to college. We are supporting him 100%. But I am already stuck on the darn registration website!

On the College Board registration, what will be the result if the responses are: “do not wish to answer”?

Where will this information go?
Does this interfere with financial aide or merit scholarships? Neither of which he would get.

The questions about classes taken, who gets this information? His special Ed school integrates class subjects, they all blend together.

I am trying the weigh if my son with ASD should take the SAT, I feel he would do well on the test. But, these questions might not lean in his favor. Thanks!
