<p>Anyone that thinks getting an extra 1.5 to 3 hours or maybe longer doesn't matter with for example a student (diagnosed with an inventive "learning disability") who might (w/o special conditions) already be at in the 1400 range - is not dealing with reality. An SAT old scale 1450 and a 1530 can be in some cases be the difference between being accepted at an Ivy League college or not being accepted</p>
<p>70 to 80 points for the SAT (old scale combined) is one estimation of the difference, and it could be higher for certain students</p>

<p>Ok - if the time doesn't matter - just give everyone an extra 3 hours</p>
