Start taking notes under timed conditions, but don't answer the questions. Use the RC1000 document just to see lots of passages. As you take notes, make sure to note the important things that will be asked about. Next read the questions and, for each, verify whether the notes you have taken would help you solve that question. Do your notes point you to where you can find the answer? Do your notes provide the information you need? You can review the other third party books on RC note taking to see what items are important.
This is important because it will let you know if you are taking the RIGHT notes. You can take paragraphs of notes, but if you aren't noting the important things that the test writers would actually ask about then you are wasting a lot of time and not truly understanding the passage from the view of a test writer. This is the phase to "understand" what test writers deem most important.
Repeat this for several passages until you start to read passages from the test writers point of view and you can detect what the important points are. After you get really used to this, you can stop taking notes and start training your mind to note the important points and track them.
This is what worked for me. Please look at this link to see another post about RC help:
