I just Beat The GMAT!

i received a private message about this thread.

it appears that you aren't approaching the RC passages in the right way. in particular, it seems that you're trying to understand everything in the passage when you read it.
that's not what you should be doing.
when you read the passage, you should *not* try to understand all the details. instead, you should just try to get the MAIN IDEA and see how everything RELATES to everything else.

in fact, this is one of the main points of GMAT RC -- they purposely don't give you enough time to achieve a full understanding of the details, because they don't want you to achieve a full understanding of the details. instead, they want you to "read like a manager": i.e., don't worry very much about details, but make sure you understand how all of the pieces fit together.

in fact, when you read through the passages, you can actually ignore all of the specifics and facts, and still get a very good idea of the main points.
here's an example:
let's take the passage from page 360 of OG12. if you ignore ALL of the specifics, and just concentrate on the transition words that indicate how things are related to each other, you get the following:
A recent study has provided clues to xxxxxx. Researchers compared xxxxxx. The xxxxx were strikingly higher than xxxxx.
In considering possible explanations for this finding, the researchers dismissed xxxxxx because xxxxxx. They rejected xxxxxx because xxxxxx. They ruled out xxxxxx because xxxxxx. The explanation they consider most plausible is xxxxxx-in particular, xxxxxx. Such xxxxxx implies to the researchers either that xxxxxx, or that xxxxxx.
even if you literally ignore all of the facts/specifics and replace them with "xxxxxx", the main point is still obvious (perhaps even more obvious!):
* research findings are described
* some explanations are rejected
* one explanation is elevated above the others
* the implications of that one explanation are discussed in detail

this is how you should be reading the passages initially.
when you get a detail question, then you should actually try to understand the details -- but only in the specific area that deals with the topic of the question. there is absolutely no reason whatsoever to try to understand everything in the whole passage; indeed, one of the main objectives of GMAT RC, from the test makers' perspective, is to select in favor of readers who can understand main points without having to wade through all of the details.

Though I really think that RC is the only part that you need to have a years of reading/understanding experience of RC, yet I thought I had this experience

well ... yes, you need to have the reading experience. the point that you may be missing, though, is that you have to have the right kind of reading experience.
i.e., if your "reading experience" consists of poring over every single detail of every article that you read, then you are conditioning yourself to read in exactly the opposite way from what the GMAT (and business management!) requires. indeed, if you practice in that kind of way, then you may be worse off than before.
try to focus on main ideas and relationships from this point forward. you may even want to ignore all of the facts/specifics and mentally replace them with "xxxxxxx", as i've done above.
