Your new best friend in learning PMP Test takes test preparation to a new level. Studying and passing your PMI Project Management Professional Test will never be easier. WE PROMISE! In fact, our amazing apps are developed by educators and utilize our proprietary learning technique ELS™ or Effective Learning Strategy. Learning, studying and memorizing requires you to use your short term memory! ELS uses a technique called “chunking.” In cognitive psychology, chunking is a process by which individual pieces of information are bound together. It is believed that individuals create higher order cognitive representations of the items on the list that are more easily remembered as a group than as individual items themselves. The bottom line… It works! PMP Practice Test comes with over 700 questions. Download the app and try it for free. We give you 10 free questions a day.
