If Spanish is not your mandatory language choice, take the Spanish placement test SECOND.
This way you will not have to pay for either of the two languages. If the tests are done in an incorrect order or you request payment track option, you will be charged accordingly.
Additional placement tests indicate languages you wish to be enrolled in addition to your degree program requirements and you will be charged accordingly.
Unless you are a DUAL BIR student: the second language also has no additional cost to you, but be prudent since dual degree programs are very demanding!
