I don't see how it's a predictor. I got 19 my first DAT when I didn't practice...I got 16 the second time around

My reading skills got worse?
RC is a lot about luck.....if a passage is about genetic diseases, the genetics majors will answer the questions without even looking at the passage, leaving them almost 60 minutes to complete 2 passages. We've all experienced (or heard of a situation) where you didn't even read the thing.
If it was a passage that ALL test takers had absolutely no previous experience with, then I'd say it was standardized. Otherwise it seems like quite the crapshoot sometimes.
But then again maybe i'm just bitter that my new RC score.....all I'm saying here is that these tests aren't as standardized as they claim to be.
