A tiring week just came to its end. Every minute was spent wisely and I still feel short of time to complete my activities. Weekend is the best time to sit down to study with complete concentration. And so, I sat to solve RC questions from Kaplan's GMAT Premier guide. Initially I was skeptical about Kaplan's method, but man, they are really awesome. Ground rules to crack RC, is clearly set in Kaplan.
These rules will just help you get closer to the answer, considering the fact that you need to concentrate on the passage as you read. Kaplan suggests a Passage Map; in addition to this, I suggest a Passage Memory Map, wherein you restate the gist of the passage in memory in an orderly fashion, and hold them for a while till you answer the questions. I solved the complete RC set of 50 questions with around 10 passages in 70 minutes.
Concentration is the key. If you don't understand a subject or if you are not interested in a particular subject, just tame your brain to pretend to like the topic and pretend to read with all interest. You are halfway through. To finish it, you just need to concentrate again ;)
