<p>Has anyone added a SAT Subject Test on the test day?
How many days after the test will you receive an invoice from college board?</p>
<p>I registered for only one test; I decided to take another subject test on the test day.
The November score will come out in 10 days but I still haven't received a invoice yet, so I'm thinking maybe I should directly mail the payment to college board?</p>
<p>Unless the process has changed in a year, CB will mail you a paper invoice that you need to pay with a check. You cannot pay on-line the way you paid for your initial registration. I do not recall the timing, but I agree with QuadMaster above and would not be concerned.</p>
<p>Consider this a bump because I want to ask the same question. Will adding a test on testing day cause the results to come out later? Does the College Board wait until you pay to release the scores to you and to colleges?</p>
<p>My son never sent scores directly to colleges using the free score reports, so I can only address how scores are reported to the test taking student. </p>
<p>CB releases scores of added test at same time as every other score. (usually 19 days after exam date). I would hope they would not prevent you from ordering score reports until they have received payment for your additional test, but I do not know how they handle that issue. </p>
