RC can be incredibly frustrating and honestly just very dry/boring. The "a-ha!" moment for me was when I realized there was no reason for me to get frustrated with answering questions about the passages because the answers are all there, right in the passages themselves. The beauty of RC is that there is incontrovertible proof in every passage that will show you the correct answer to any given question, and all you have to do is find it. It's not like you have to remember grammar rules, definitions of weird words, quant strategies that you made yourself memorize-- it's almost purely a test of focus, which is both liberating and frightening, I guess.
Keep in mind that the answer is there to be found, for every question. GMAC has to write each question so that if any student comes back to them and says, "this 'correct answer' is wrong", they have to be able to point to a sentence in the passage that provides definitive evidence for their correct answer.
In these last two weeks, I would recommend a lot of RC practice (especially OG material), but also taking productive study breaks by reading articles online from The Economist
and Wall Street Journal to get into the habit of reading long, dense passages, like you're likely to find on the GMAT. Hope that helps!
