<p>I decided to take the SAT Reasoning Test on Dec 6 instead of the SAT Subject Test.
Has anyone experienced changing a test type on test day?</p>
<p>Does it take longer to receive the scores?
How much is the bill? $22?</p>
<p>You CAN change your test type on the test day, as long as there is still space available at the center you are supposed to take the test. My experience: early birds catch worms. So, just come early, if necessary, earlier than other people.</p>
<p>The fee for making this change is $21.</p>
