I took it yesterday. My paragraphs for each were 14-17-14, ones where I practiced were about 6-12 so I was shocked, I had a mini panic attack lol. I ended up somehow scoring a 24 on it, and I believe its because since they include so many paragraphs, they ask more content questions than inference questions, which are alot easier. My articles were about transcription/translation and some new type of study regarding mrna (probably the hardest one, most inference questions), then one about channels, such as voltage gated, ect. and messengers and what not. I saw that there were 17 pg's and was really afraid but ended up up being ok. Just make sure you label what they talk abt in each pg so its easy to go back to. My last pg was something about the brain and the functions of each part of the brain. I'm thankful I did not get that piano article that people are afraid of. good luck!
