Should take about a month to master. More if you don't take out at least 2 hours for it.
For RC my strategy used to be a mixture of the ones I used with the Jamboree's youtube playlist, Manhattan's and Veritas with a little twist of IELTS technique.So for RC reading, we will adopt the STOP strategy by Veritas that they have discussed many times in their youtube sessions. Under STOP strategy, you need to understand the S- Scope, T-tone, O-Organisation and P- Purpose of passage while reading it. Now using this technique requires active reading. When you start reading, and read the first statement, make a judgement that the passage may discuss about something in those lines. For example, in this first line- "Thomas Hardy’s impulses as a writer, all of which he indulged in his novels, were numerous and divergent, and they did not always work together in harmony." In the line, it is pretty clear that the passage will be talking about this Dude's writing style. That pretty much sums up the tone as judgemental and probably the author will take sides. Now read on keeping that in mind, read the second line and see how it connects with what you guessed. "Hardy was to some degree interested in exploring his characters’ psychologies, though impelled less by curiosity than by sympathy." It connects well with what you guessed, the line is indeed judging his writing style. Then do the same with the entire paragraph. Initially, when you read RCs, you may want to use a notebook to take notes and see how the lines connect, what you were guessing (wrong or right), what you missed to guess etc. When you solve enough RCs, you will get good at doing the mental mapping in your mind.After every paragraph, stop and think how things unfolded, let's see it this way. "Thomas Hardy’s impulses as a writer, all of which he indulged in his novels, were numerous and divergent, and they did not always work together in harmony. Hardy was to some degree interested in exploring his characters’ psychologies, though impelled less by curiosity than by sympathy. Occasionally he felt the impulse to comedy (in all its detached coldness) as well as the impulse to farce, but he was more often inclined to see tragedy and record it. He was also inclined to literary realism in the several senses of that phrase. He wanted to describe ordinary human beings; he wanted to speculate on their dilemmas rationally (and, unfortunately, even schematically); and he wanted to record precisely the material universe. Finally, he wanted to be more than a realist. He wanted to transcend what he considered to be the banality of solely recording things exactly and to express as well his awareness of the occult and the strange" The passage started by saying something about the author's writing style and how they were versatile, then all the other lines describe these versatile things.
Your next task is to put a Label on the paragraph, give it a short name. In this case, I'd say "Dude's versatile writing styles"
Now repeat the process with paragraph two and three and if you're unlucky 4 and 5 too. After you're done, take a step back, and reflect back on the organisation of passage as a whole.The headings you put will do that job for you, you can see how the passage evolved. It started by describing the writing style and if you search for the passage it then evolves in how he used these styles uniquely and then ends with suggesting that his novel writing was uneven and suggests an example of that case.
So, you're reading part is complete. Now the connection between the lines can help you solve the inference questions and the highlighted questions, the organisation is enough to give away the primary purpose questions and the according to... questions can be answered by rereading after going to the part that is mentioned.
My advice in general when you narrow down to two options is to start looking at the exaggeration, adverbs and adjectives used and the difference between the two options in those terms. In case you do come down to two of the absolute close choices, as is designed by GMAC, you must find the difference between both the choices and then re-read to see which one the passage favours. You should not try to read and then select the answer in such cases. Usually the wrong answer uses "extreme" language such as "best", "the only way". Unless stated in extreme language in the passage too, the choices are usually incorrect.
When you solve, keep a track of these things.Make a note like this-
A. Wrong because xyz
B. Wrong because xyz
C. Confusing because pqr
D. Right but got confused because of pqr
E. Wrong because of xyz
