<p>i took two subject tests this month
i registered for only one subject test and added one more at the test center
they told me that collegeboard will bill me later but
i haven't gotten anything from collegeboard
the scores are coming out next week and i heard the scores will be withheld till i pay
so... is there anyone who have added a test on test day and got the bill??</p>
<p>how am i supposed to pay???</p>
