That's where everything falls apart. I do well on EK (10/11) but on the AAMC diagnostics I'm between 7-9. Remember though, there are still 40 questions overall so if you have a lot of questions in one passage, there must necessarily be less in another. EK will have 5-7 questions on each and AAMC is just a crapshoot so it I just average between 6-7 minutes on EK, I never really took my time on AAMC because I hate watching the clock. I usually finish with about 10-15 minutes to spare on the AAMC's but I got my questions wrong because I can't tackle humanities. AAMC 8 (brutal verbal) I had 91% on soc sci, 80-90% on Nat Sci, and 35% on humanities. My problem was that I rushed my reading and didn't understand the complex articles. Once you understand the articles well answering questions doesn't take long. The time I got 9, I was already burnt out, I was surprised I did so well because I pretty much gave up halfway through (I wasn't reading for detail, I was specifically searching for the stance/argument because my brain couldn't take anymore detail absorption).
