Some recent recommendations

Here are some recent recommendations for Pick of the Day, the links to which I am providing in a joint posting today, together with some basic information about them provided by their creators

• Free Math  from Brightstorm
  "We've gathered great math teachers to film concise, engaging online videos for every topic in the high school math curriculum (Algebra 1 through Precalculus, and Calculus is coming soon).  With over 1,800 free videos, we think Brightstorm can be the place where learners come when they are confused about a math topic."
• Visual  PMBOK Guide
  "I created the learning tool out of personal frustration with the state of resources for mastering the Project Management Institute’s A Guide to the Project Management Body of Knowledge – Fourth Edition."
• Ctrl Alt Del
  "This month , I launched a brand new e-learning website for anyone to become a Microsoft Certified Professional (MCP). It's ad/spam/pop up free and has the following benefits: 40+ How to videos; Over 40 practicals; Over 100+ questions to test your knowledge. Its free (for now) straightforward and jargon free!"
• LearnGrid
  "Our aim here is to build job oriented courses and offer them for free. We also intend to allow organizations to use the LMS/Assessment engine/ Authoring tool for a very small monthly charge just to cover the maintenance charges."
