From the press release:
XAMonline.com, a leading publisher of teacher certification study guides, today launched the IntelliGuide™, a new cutting-edge technology product that will redefine how students and professionals use eBooks and prepare for their exams. IntelliGuide™ is an online platform that transforms the traditional eBook experience from simply reading a static PDF to interacting with an enhanced study guide and test practice session using innovative tools such as printable eStickynotes, highlighter capability, pre-made or user-generated eFlashcards, and timed, scored, and hyperlinked practice tests.
Additional product features include a personalized study plan with check boxes to track progress and identify content areas for improvement; multiple, timed practice tests with the option to pause and hyperlink back to relevant content; easy navigation of previously viewed content using the “History” sidebar; and a search feature that enables users to quickly find the content they need within the guide. The eFlashcards allow users to study pre-made cards or create their own. The “Hide” function enables them to skip cards they already know, creating a customized study experience.
