Hey phoenixreborn, absolutely you can keep an error log
One quick tip: the most common reason I've seen that people miss CR questions is because they misidentify the conclusion (the author's main argument). One example I use is from the OG Verbal
Supplement, CR #54. What's the conclusion of this argument? Go try it now, then come back and read the spoiler.
Many people say that the conclusion is:
"Tanco should switch from salt to potassium chloride."
But that's not what we're interested in - a better conclusion is:
"Switching from salt to potassium chloride will be profitable for Tanco."
Notice that only the second conclusion allows you to identify the correct answer, (E), as being irrelevant with respect to profitability.
To start your error log
, what I recommend is to write down what you think the conclusion is for every CR problem you see (except the draw-a-conclusion questions or minor types that don't have conclusions). Then, if you miss a problem, see if the conclusion you wrote was correct. If not, what would have been better? Could you have been more specific? Did you really understand the logic of the argument?
There's plenty more that you could keep in your error log
, but this should get you started. I'm curious to hear from other GMATClub members as well - what kind of notes do you keep for CR problems?
