All questions are from this dumps. I just go through the whole material. Only prepare with this dumps and passed my exam yesterday with 80%. I bought dumps from other sites, too. The dumps from this site is the most valid and accurate one. I bought the VCE format. One thing to remind: the VCE can only be used with Windows, not Mac or your smart phones.
