Heygirl, I think quite a few people for whom RC is a weaker area would share your frustration-- RC is often difficult to achieve significant improvements in, especially within a short period of time (whereas in math you can memorize formulas for geometry, for RC you may have to reteach yourself to do something *differently* that you already do every day-- process information as you read).
You seem to already have a good pool of resources in terms of books, so I'm going to take a different tack and try to explain why the note-taking is helpful for many people. If these reasons are not applicable to you, then by all means don't use note-taking! Every student is different, and there's no "right" strategy, other than the one that gets you the most points in the period of time you have allotted to study.
And when I say "notetaking" below, I mean "good notetaking"...more on that after the points:
*Notetaking helps you stay alert. For people who struggle with RC, a huge part of the battle is just preventing their eyes from glazing over while reading large chunks of text. The physical act of putting pen to (glossy yellow laminated) paper keeps you awake.
*Notetaking helps you synthesize information as you're reading. Aside from the physical alertness-aid, the act of having to quickly distill what you've read into its crucial parts helps that information sink in.
*Notetaking provides a repeatable process that creates comfort zone that allows you to do your best work. Why do certain math questions seem so "hard" and others "easy?" If you recognize what kind of question you're confronted with, and have a repeatable process to execute on that question (because you recognize the type!) your job is much easier-- execution of something familiar rather than working through something for the first time. Reading passages can be that way too-- the long passages are, well, looooong, and notetaking gives you a tool and a *structure* to stave off that feeling of words flying at your face.
So what is
good note-taking for long-reading? You can ascribe to one of the test prep company note-taking methods--all the methods worth their salt provide a
repeatable, structure-based process to create a way to hold any new information you're faced with on RC. Try a bunch, and see what feels best to you (and yields the best results)--the goal is to arrive at a method that allows you to process just the right about of information *for you.* Some people are front-heavy and need to learn to let go of details, others are question-heavy and need to learn to focus a little more on the passage before. It's a tricky line to toe. But either way you must give yourself the time to really give the methods a shot before discarding them-- reading work may not yield instant points the way some math work can, because what you're working on is *process* (you're working on process on the other question types too, but a larger portion of the work for those other types involves content). It will be slow at first, but getting better will help you get faster--the reverse isn't necessarily true.
This is all, of course, assuming you have the time to devote! If you've only got a week til your test it's a
different ballgame, and unless RC is your only weak area you can probably achieve a higher points earned/time invested ratio on other topics At a certain point too, you will know that you've plateaued and your time may be better spent elsewhere.
The practice, practice, practice method you're suggesting can work for some people, if they're super-vigilant about the *review* of that practice. The thing you want to avoid is burning through tons of materials without analyzing your process. I see that a lot--many hours invested with little payoff. And even with detailed work to RC-passage process, you'll want to spend quality time working on doing and reviewing OG questions. A lot of the attention-to-detail work that can be done on CR is applicable to RC, too--a word here, a punctuation mark there...learning how and in what ways the test-writers are anal-retentive will yield points across the board.
Good luck!
