They make it in a way to make sure if you are selecting a correct answer, you know why is it correct. I studied for 55 days using Sybex 7th Edition. That is the only book I used, no videos or any other book. Got the latest released official practice test a week before the exam and practiced them.. Note: End of chapter and Practice tests are to make sure you know the concept... exam questions are to make sure you can implement that concept in a real situation. Good Luck to all..
