Caltech - Should I self-report scores?

They don’t need any official SAT scores from College Board, their admissions office even told me sending them would be a waste of money.

I can leave the self-report section on the Common App blank as well. But should I?

I got a 770 in reading, 660 in math, 660 in writing, 620 in chem, and 690 in literature.
I took these tests two years ago in HS.

Thanks!
