<p>Since we are in a SAT part of the country, I have no idea. How likely is it to get closed out of a testing center within a reasonable drive? How early do you need to register for the testing dates? Can you register for October and wait, or do you risk getting closed out of December and the other dates that follow? BTW, we do not have tons of centers to chose from (maybe 2-3 near us per date). I realize that the money is not refundable if you decide not to test for later seatings (except for the extra services like the Q&A booklets).</p>
