I downloaded the Brutal SCs (sentence corrections) listed in the forum and have answered a few (wrong). Does anyone know where these came from? Are they in fact valid? It bothers me that there are no explainations with the answers. I wanted to verify that they are in fact not just some random assortment that some person with a poor command of GMAT english put together as what he thought were hard questions. Any feedback on this one? This is where wiki's tend to scare me off - when you don't know anything about the content and its validity.
