Description:The chapters have little substance, but that's just the beginning. Aside from the choppy sentences that almost look like they were written by an ESL student, the Review Questions are simply terrible. They don't actually measure your knowledge and ability to apply the information. They just flat out suck. Steven Johnson might as well ask questions like "What am I thinking?", or perhaps list challenges like "Guess what's in my hand." Either one of these would be more challenging and relevant in preparation for the 70-647 exam than his mindless drivel. Therefore, Mr. Steven Johnson, I award you no points. And may God have mercy on your soul.
