I first heard about this from Zain Naboulsi back in January and am finally getting back to blogging about it.  MSDN has a developer learning program called Ramp Up that they describe as follows:

Do you want to gain new Microsoft .NET development skills, but aren’t sure where to begin? If so, MSDN Ramp Up is the place to be.

Through a solid foundation of premium technical content from renowned experts, Ramp Up provides the step-by-step guidance and in-depth learning content you need to build your portfolio of professional development skills.

Basically, you choose your track (most likely the Visual Studio 2008 Tech Ed Track for most people reading this blog), complete that track, and then at the end you get a "Graduation Award" consisting of a 50% discount on exam 70-536 among other things.  That exam is the first exam on the road to a number of Microsoft Certified Technology Specialist (MCTS) and Microsoft Certified Professional Developer (MCPD) certifications for developers.

Hope this helps and good luck!
