600-700 level questions in Quant

[thill287]

Hi,

I am looking to brush up on Quant questions at this level. I seem to be getting 50% right and 50% wrong, especially in Algebra, and Geometry. Any advice?

Why are you getting those questions wrong? Examine each question and really articulate exactly what the weaknesses are. Are there formulas or rules you don't know well enough? Are you making calculation errors with things that you do know how to do? Those kinds of things are content or skill errors, so you would need to go and do some drills, make flashcards, and that kind of thing to get better.

Or are you fine with the content and calculation skills but struggling to answer questions in the often strange way that the GMAT writes its questions? Do you look at these questions and think "I don't even know what they're asking!" and then when you read the explanation you think, "That's what they were talking about? I knew how to do that but I didn't know that's what they wanted."

If so, then your struggles are more about how they word their questions, so you actually need to study that. Go through OG questions and make up flashcards that say "If I see this..." on one side and "Then I'll think / do this..." on the other side. You're teaching yourself how to "translate" GMAT-language into normal English. :)

Most people struggle with both aspects, so chances are the same is true for you. Really, you just need to go figure out WHY you missed a question, and then that tells you what you need to study or practice in order to get better.

Also, do you have books you're using to teach you how to do the math found on this test? Eg, we have a book for algebra and another for geometry, and each teaches you what you need to know for that type of problem on the test. You'll need some resource like that in order to use when you discover a particular weakness.
