Note: If you want to substitute Subject Tests, you should do that at the test center. You may substitute any Subject Tests offered except the Language Tests with Listening.
BUT it doesn't say if this is free. The fee for a test change is $20.50, if I have to pay that, I might as well fail the one I signed up for and pay $8 for another test.
Does anyone know from personal experience? I really don't want to take a test that I know I will do terribly on. I hope that I could change a subject on the testing day, and it's not a language test.
Thanks for your help!
