There is a comparative RC passage, so it is definitely recent. Also, the LR questions were worded like the 60s and 70s.

@alexandergreene93 That's how you measure the difficulty of an item in metrics, the percentage of people who get it right vs. the percentage of people who get it wrong. But you're right I'm banking on 7sagers being a reliable sample though
You cannot tell which section is the experimental. If you could, people would take a thirty-five minute nap and the test-writers would have no way of assessing the difficulty of the exam.
@"Ron Swanson" What kind of timing strategies are you trying out? I tend to run out of time for RCs, pretty much leaving the fourth passage blank. I sometimes miss 1-2 questions on LRs depending on their difficulty levels.
The best prep for RC is reading a lot of RC passages. You have more than 300 passages, already the perfect length and subject matter (not to mention level of difficulty).
