How to review RCs?

Hi KB04 and mrinal0308,

abhimahna has made some great suggestions. Here's what I would add:

Your goals in RC practice:
1) Learn how GMAT asks questions
2) Learn what differentiates a correct RC answer from an incorrect one and how GMAT has arrived at that correct answer
3) Identify potential weaknesses with specific content types (scientific, for example) so you can do outside reading in that area

For any type of RC question other than a Main Idea, you should be able to point to a specific part of the passage that provides the evidence for your answer choice. When practicing, you might try writing a short note to yourself about where you found the evidence (say, line 20).
Then, when you review, even if you had the correct answer, check to see if the OG references the same evidence you used. If not - why? Why didn't you choose the same evidence they did? How can you change your approach to look for that type of evidence in the future?

(Note: I don't recommend noting the line number of evidence during an actual exam, but it can be good during practice to help you analyze where you are going wrong, AND to build your discipline that the answers to all RC questions except Main Idea MUST be based on evidence.)

For Main Idea questions, you might have specific evidence in a thesis sentence, but not always, so don't expect that there will be one specific piece of evidence to point to. Sometimes the correct answers in RC, especially on Main Idea questions, are unsatisfying. Many candidates eliminate a correct Main Idea answer because it seemed too vague or general, and instead choose something that sounds more specific. However, there was something about that specificity that made their answer choice wrong. Is this happening for you?

You mention that you are using an Error Log, which is great, but only as good as the data you put into it. Try to be as analytical as possible about exactly why you chose certain answers, and what was wrong with that reasoning or technique.

Let me know if this helps!

Best, Jennifer
