Hey AbhiJ,
Based on my experience on these forums, I'd add this - and I don't think it's necessarily right to paint "non-native speakers" with the broad brush, but I'd certainly say it's true of "most non-native speakers who are active on Beat the GMAT".
The group you mentions tends to thrive on rote memorization, and to do it really well. That's why they'll often write about how many times they've read Manhattan SC or Powerscore CR or how many practice tests they've done. Their emphasis is on "knowing information" and not nearly enough on "how to do GMAT questions". So they:
-Read RC inefficiently, trying to understand most/all of the details in each passage
-Miss big-picture SC errors (illogical meanings, etc.) focusing instead on obscure idioms or plug-and-play strategies
-Struggle with clever CR problems in which their tried-and-true diagramming, etc. strategies don't spit out the correct answer right away (you'll see this a lot with "strengthen" questions that strengthen by introducing a roundabout weakness and then refuting it, or with those that begin with a 12-word out-of-scope modifier before getting to the point)
I'd argue that most of those in the crowd you mention are missing questions because they're focusing their energy on the content knowledge that surrounds the GMAT and not on the higher-order thinking skills that the GMAT truly aims to test. That group also tends to have quite a few students who are so incredibly good at math that they may not have to think too higher-order on quant questions because they can brute-force a lot of it, but on the verbal that's a lot harder to do (if even possible).
Keep in mind that RC passages are capped at a fairly short length (according to OG12 it's 350 words), so it's not a case of the computer trying to wear you down with massively long passages. I'd argue that most of what you're referring to is caused by people's attempts to *know* their way to success on the test and, in doing so, missing the opportunity to *think* their way there.
