I'm a slow reader as well. If I feel like confirming that, I might take the test.

I have a short attention span, I'll read two or three pages and come to the realization that I have no idea what I just read and have to start over again. I want to be a reader, my undiagnosed ADHD thinks otherwise.
My wife OTOH is a fast and voracious reader. She'll blow through a novel in a few hours over a weekend.
