Learnist: Introduction to “Flaw” Questions on the GMAT

Flaw questions on the GMAT follow predictable patterns: the flaw usually lies in how the evidence is being interpreted, or how the evidence was obtained. No one ever said the GMAT wasn’t flawed. 🙂

This video introduces you to two of the most common logical flaws you’ll see on the GMAT: “If not P, then not Q” (double-negation) and “If Q, then P” (reverse). Be on the lookout for these in the incorrect answers of Flaw questions!

This lengthy MGMAT article covers 4 types of flaws to look out for on GMAT CR: – Confusing Percents & Numbers – Causation – Out of Scope (“Limiting” words) – Evidence/Conclusion misalign

In this sample question, we’ve got an issue with the evidence/conclusion not being focused on the same thing. The conclusion is far too general, trying to apply one instance towards an overarching rule. Notice how their focus is just not the same — we could also interpret this as being “out of scope.”

Even on a CR question, you might see a little Math! This article focuses in detail on what to do when numbers appear in Flaw questions. The important point: keep in mind that a smaller percentage of a larger number can be greater than a larger percentage of a small number.
