From what you describe, I think you're reading / paying too much attention on your first read-through.
Pretend you're sitting at your desk and your boss pokes her head into your office and says, "Hey, kouranjelika, before our meeting with our new client, can you run through the press releases on their website over the last couple of months? Just make sure we know the latest about the compay."
You say, "Sure!" Then she adds, "Oh, and the client's going to be here in about 5 minutes."
Uh....
So what do you do? You don't tell your boss "Sorry, can't help you." You don't blow off the assignment. What DO you do?
Most people will say something like: I'll look at the headlines; I'll only look at the ones that are about financials or product announcements (or something specific); or even I'll scan all the headlines and pick the 2 or 3 that I think are the most important and skim those.
The point is that you would NOT actually try to read every sentence (or even every headline, depending on how many there are). You'd prioritize.
The GMAT is like that. You can't read this whole thing carefully in 3 minutes. We know that! That's not what we're trying to get you to do. :)
Instead, we're trying to get you to take in just the "headlines" - what are the main points of the passage? What are the big contrasts or changes of direction?
When you get to detail - an example to support something or whatever - think to yourself, 'Yeah, yeah - I might come back to you later if my boss asks me something about you, but not right now. Shhh, don't distract me. I don't have much time!"
You're in our class, so you have access to our OG Archer program. Take a look at the video explanation I shot for the second-to-last passage in OG13 - the one about plant hormones. That passage is brutal. Look at how much of it I skip / skim on the first read-through.
That's what you're trying to do. You're not trying to learn how to read carefully but reallyreallyfast. :)
Re: note-taking, if you can keep a good mental map to know where to look for certain details, then it's fine - you don't need to take notes. But that's really all the notes should be doing for you anyway, mapping the passage.
You want to be able to say: that detail about pesticides? That's in paragraph 2. I don't know what it actually
says about the pesticides - but I'll figure that out later if (and only if) I get a question about it. If you can remember that while still skimming / not reading everything carefully, then great. Just remember that it's harder to keep that Mental Map when you're going more quickly and skimming over stuff.
Note that you talk about doing really well when you're doing the 5, 7, 9 questions that come with the passage. That's not a good measure, because the real test will only give you 3 or 4 of those questions. So, first, you spent a bunch of time upfront reading / learning about details that you will NEVER get asked about in the questions. Second, you will also never get the "later question" advantage - questions 5, 6, 7, 8, 9 become easier because you already know so much about the passage. But the real test is going to stop you at 4.
Okay. So, you have my permission to drop the notes as long as you can consistently keep a rough "map" in your head of the passage. :) If you discover, though, that this ability starts to fade when you start to skim (more on this below), then you've got to start to take a few light notes, but you have my permission to jot down no more than 3 or 4 words per paragraph - just to remind you what that paragraph is about overall.
On the reading, as you know, you just can't spend that much time - the test won't allow you to do so. So you need to change your mindset. This is not "Just read the same stuff but faster faster faster!" Rather, it's: if your boss only gave you 3 minutes, how would you decide how best to spend that time? Only pay attention to the things that are worth your time - let the rest go.
Take a look here at the "what to read and what not to read" articles (and look at that video I was talking about earlier). Then come back here and tell me what you think.
