Can I switch the type of SAT (from subject to regular)

Test Preparation
1

I signed up for Subject Tests on October 7th, however, I do not feel comfortable enough with the content. Is there any way I can switch them to a regular SAT without having to change the test date?

Yes, but there is a fee.
