<p>Possibly offpoint, but there is a big difference with leaving answers blank, and not finishing. The SAT math problems, for example, increase in level of difficulty. For average joe/jane high schooler, the last ten problems will be extremely difficult, and more time won’t help that student to solve those problems. The student is much better off spending time rechecking the “easy” and middle difficulty problems to increase his/her score.</p>
