<p>Does anybody have any hard proof (web link) that specifically indicates how the SAT curve is determined (predetermined or like the APs, determined based on overall score)?</p>
<p>it's determined before hand...its somewhere on teh cb website</p>

Are some SAT tests more difficult than other ones?
All editions of the SAT are developed using the same test specifications. Even if there are tiny differences in difficulty from test to test, a statistical process called "equating" ensures that a score for a test taken on one date or at one place is equivalent to a score for a test taken on another date or in another place. The rumors that the SAT in one month, say in October, is easier, are false.
