Maybe others can attest to this, but I find the passages in the reading section is comparable to the words used in the scientific journal articles (not like in the scientific aritcle format, abstract, intro, materials, results, discussions).
My three passages for my DAT #2 were:
1) Diabetes Mellitus
2) Fatty Acid absorption
3) Clotting and Innate Immune System
Lots of big words and scientific names/ligual!
Also, I read the questions and search for the answers, I do not read whole passages! Test to see what works best for you! The passages are usually broken down into specific sections for certain info/topic. Usually each paragraph of that specific passage is a different topic for that theme.
I did not spend time studying for this section at all! I figured that since I search for answers (that works the best for me) instead of reading the passages, there's not much I can train myself to enhance my "searching" skills!
It's funny that, once I've found all the answers to the questions for the passages, I learned what the passages are all about at the end! I strongly feel that read "Q"s and search for "A"s is the best way for me!
DAT #1: 19 in reading
DAT #2: 23 in reading
