<p>…Would it be possible not to take one of them and still take the other?</p>
<p>Yup. NO worries. You can pretty much do whatever you want on the day of testing with SAT IIs. You can add one (they’ll bill you), delete one (I don’t know if you get money back or not), change the subject you’re testing, whatever you want. Just tell your proctor. And read up on it…some of the proctors can be clueless about the rules. Just go to Collegeboard and look it up.</p>
<p>No money back</p>
<p>SO ,basically you can go to the test center and without being registered for any test AT ALL ,you pay and then you are given a test of your choice ?</p>
<p>No, you must be registered for a subject test</p>
