CR Section: Speed versus Comprehension?

<p>I've finally reached the point where I'm stuck. My highest score in the critical reading section is 720, and I <em>can't</em> do any better.
The problem is that I've always been a very slow reader, and I've definitely tried to read faster, but then, even though I can (sort of) understand what I'm reading while I'm reading, I forget most of it.
On the other hand, when I read at the pace I normally read, I can understand and remember just about everything, but I end up finishing dangerously close to the time limit. </p>

<p>I only have 3 weeks before the PSAT. Does anyone have any tips for reading faster while still understanding and, for the most part, remembering everything?</p>
