This is another great question, when it comes to the practice tests, they will scare you at first, I know they have got my attention before as well. They are structured to give the exam candidate and idea as to how prepared they are ( or might not be), and more importantly where to focus your study time in (i.e. which domains/objectives you are weak on). When looked at from the perspective that you where right around 4-10% off from passing the practice test on the very first try, says a lot about your study methods as you are very close. It is advised to take the areas in the "post-score breakdown" that you are the weakest in and research those areas more in depth. The content that we provide is comprehensive but not completely exhaustive. However we always recommend that additional methods be added to the exam candidate's bag of study tools. This is why we have the added value of Practice-Labs.com and practice tests to supplement the members training. I would also recommend using additional prep material such as FlashcardMachine.com, Quizlet.com and our forums here. There are also books that provide extra material such as ExamCram. I hope this helps and please keep us informed on your progress as you most certainly do not have to go at this alone.
