Quick Question Regarding Score Choice

Is it true that colleges can see the SAT/SAT2 scores even if you did not send it to them through Score Choice?

Say that I scored a 800 on Physics and a 600 on Chem. If I just sent the 800 Physics via Score Choice, will the college be able to see/find my 600 Chem in any way or is that impossible?

(Because I heard rumors that even if you do score choice, colleges can still see all your scores)

Colleges only see what you send.
