<p>if your main weakness lies in Reading Comprehension, memorizing 2000 words probably woundn’t do much good. You stated that you’ve done “Lots of Practice.” But have you really taken the time and effort to carefully analyze EACH AND EVERY mistake you’ve made? Have tried to find out WHY you made those mistakes? Practicing only accounts for half of successful score. The other half is about thoughtful analyses.</p>
<p>2000 words could help the sentence completion, but I don’t think it will help all that much. you need to work the problems in context. straight memorzation won’t help unless the actual word is on the test.</p>
<p>Being strong on vocabulary IS definitely of great advantage. It helps you coast through the sentence completion sections(though sometimes this part also requires logical reasoning) and have a better grasp on the passages (needless to mention its usefulness in the what-does-this-word-mean questions).
Trust me all people I know who got sparkling scores on CR have a very solid vocabulary (acquired through constant reading) :)</p>
