PHP Developer, IL
I would like to recommend uCertify and their services. I have been a CTO at a few companies, currently working as a PHP Leader Developer after using their PHP5.3 ZCE PrepKit.
This product is absolutely perfect. I tested many kinds of software from other companies and I want to say that this is my favorite one. Also, their support is amazing – they responded to my questions in a very short time and answered them with just one email message exchange.
If you wish to get good service and a good test prep product, this is the company I’d recommend. I have recommend them to all my colleagues and partners and they agree with me : )
