Help with Subject test Registration PLEASE

Signed up for the November 5 sat but I can’t seem to get the subject tests on the same date. The earliest date possible is Dec 3 not Nov 5 when I try to sign up for sat 2s, but the thing is when I go and change my sat registration from sat to sat subject tests Nov 5 becomes an option. How do I get my sat 2s on Nov 5?

nevermind you can’t take them on the same day.
