Someone left a comment stating that this guide is not free. I'd say using this digital format, not the PDF document, is free. I'd also add, with all due respect, that no one should expect to receive a freebie study guide in the mail without a price, and that is because such documents do cost the producers some money.

I am pleased to let you know that I passed this exam last Friday. Here are some feedback to share: 1- The exam is tough so you must read and read and prepare 2- They give you enough time. Skip the questions you don't know and come back to it at the end. 3- Use this exam dumps. I saw most these questions in the exam. Good luck.
