How do I get better at structural reading in Reading Comp?

So glad you asked.

Here are three methods (you should use them all, at least a little bit):

1. Backsolving. Start with the right answer choice for the Main Point and Primary Purpose and Organization question/s (where present). Now you know what the test writers think of the passage: use that to find where the test writers got their support from the passage itself. Think about why they wrote the right answer they way they did. think about how they tried to be tricky in writing wrong answers. This will help you become a more structural reader, but it will also help you develop some insight into the test writers' frames of reference about things!

2. Mimicry. In every RC practice video, I begin by discussing the SPAM of the passage, with some brief notes about anything else I found interesting (I think this is true without fail; you can let me know if you find any place where I didn't do those things). Do what I do! Watch me do it a few times, then do it on your own and compare your work with mine. What did I find important that you left out? What did focus on that I omitted as not big-picture helpful? Whydid I leave that thing out? Now, in addition to thinking like the test writers, you're learning to think like a great test-taker.

3. Finally, think about how you'd teach someone else: what would you say was important for your student to notice about the passage? Take your time with it. Don't worry about your speed—just spend all the time you need to locate the answers within the passage, and think about how each right answer reflects the main point of the passage. Think about whether the passage evinces any of the patterns we've looked at so far. That's structural reading!
