Consider the subject tests in the context of the rest of the application…if it makes the application stronger, send the scores. If it doesn’t make the app stronger don’t send. If neutral…probably doesn’t matter if you send or not.
Double check what your schools are doing wrt subject tests…I don’t know any that have recently changed their stance (meaning for upcoming 21/22 cycle) except for MIT, CalTech, and Harvey Mudd…all went from requiring subject tests to being test-blind wrt them.
