Regarding time management: I suggest that you manage your time in batches of 5 questions. To that end, you can use the following Milestone Charts to keep you on track:
These times are easily remembered so you can quickly jot them on your noteboard on test day.
This (and more) is covered in our GMAT time management video at
https://www.gmatprepnow.com/module/general-gmat-strategies?id=1244Regarding note-taking when reading an RC passage, I believe you should identify and summarize:
- the theme of each paragraph (4 to 8 words)
- conflicting points of view (4 to 8 words)
- main idea (4 to 8 words)
So, we're talking about 20 to 30 words altogether (and you can use shorthand and acronyms to use fewer words).
If you take good notes, you won't have to go back and re-read the passage. More importantly, when you're looking for specific pieces of information to summarize, you will better engage with the passage (which is a HUGE factor in RC success).
