HanoiGMATtutor thanks for getting back to me. I will do my best to describe how I approach CR questions.
1. I read the question itself and try to categorize what question type it is, i.e. Assumption, Weaken / Strengthen, Inference, and so on. Once I know the question type, I prepare myself to look for patterns that I learned from PowerScore CR Bible and some other resources such as youtube videos by GMATNinja and Ron Purewal.
This usually takes no more than 10 seconds. There are instances, though, when I fail to dissect what a question is really asking, and can spend about 30 seconds trying to understand what I should look for. In most cases such questions are easy to answer as long as one understands what question type he / she is dealing with.
2. I read the stimulus and, unless I am really behind on time (applies to test only), take short notes. I abbreviate aggressively, and will usually put (C) when I hit the conclusion, and also take note of a cause and effect diagram or of a sufficient and necessary condition.
For example, if the sentence says "To receive a high score on GMAT one must study thoroughly and learn time management techniques", I will note this as "ST & T mgmt -> HS".
I do my best to understand every single piece of each sentence in the prompt. If I don't get what the sentence is saying, I may re-read it again (this does not happen very often, but happens about 25% of the time on hard questions). I also pay attention and jot down indicators such as "however, but, yet, for example, etc."
I guess reading takes about 60-90 seconds, depending on the question difficulty.
3. After I finish reading the prompt, I usually think for about 10 seconds and try to digest what I read and connect facts to conclusion. Then I go to answer choices. Sometimes I have a clear idea what I may need (e.g. if it is an assumption question), but sometimes I do not know what exactly I need.
4. I start reading every answer choice and try first eliminate those which are completely wrong (out of scope, opposite, reverse, or too strong).
I would say that 75% of the time I am able to eliminate 2 or even 3 answer choices quickly, but then I might get stuck. In a very bad case, I may not understand the stimulus and then all answer choices look the same to me, and this is reasonable because I jumped to questions without understanding the prompt. I guess in such cases the best decision will be to bail and move on, because there is not much I can do.
1st round of answer choices reading takes about 30-45 seconds. If I get stuck, I may spend more time analyzing the contenders.
Total time spent is between 2 min (10 + 60 + 10 + 30 = 120 seconds) and 3 min (30 + 90 + 10 + 45 = 175 seconds).
Is there anything that you think is totally flawed? What approaches can I try to make myself quicker and not loose the accuracy?
