Passed GCIH! Read the books twice and listened to the mp3s once. I do believe the exam was much harder than the practice exam. I had more real case scenerios and screenshots of the output command. I used 50% of my index and the rest went with my gut feeling. Glad it’s over, a lot of info sink in.
I think it the luck of the draw, I firmly believe the questions are pulled from a pool of possible questions. It makes sense, since there is a slight lag sometimes between questions, I believe it's the server selecting the next question and sending to your testing center PC, If the entire exam was sent to your test computer at the beginning of the test before asking you your first question, there would be no lag between questions.
