<p>Ok so I am signed up for only one subject test (USH) for June. But I would like to take 2 subject tests on this day. Do I just take 2 of them when I am there? Do I need to tell the proctor I am taking two. I think I heard that college board will just bill me later, is that correct? Anyone who has been through this, please let me know. Thanks</p>

<p>just take both tests, no need to tell your proctor you are adding one.</p>
