I love reading comprehension so wanted to jump in and share some quick thoughts. I find taking notes a strict no-no because
1. They take my eyes away from the most imp thing which is the screen(and the passage)
2. If you dont follow/understand the passage, making notes is not the equivalent of a magic pill that will suddenly make the passage easier for one to understand.
3. The passages are never long enough for somebody to actually realize any kind of value from this note making.
What works for me is
1.reading/ re-reading the passage and making mental summaries. I never shy away from spending extra time if needed on any RC paragraph.
2. I always try to have a main point from each para. If the passage is too difficult, I just remember what I think is important and then try to work backwards from the questions.
I can see my approach is a complete 180 to
bb 's approach, so sorry if my post doesnt help you a lot.
