Just back from the MS Project 2012 Conference in Phoenix, where I passed exam 70-178 (Microsoft Project 2010: Managing Projects). This exam results in the MCTP credential.
Microsoft states there no official study materials or practice exams exist for 70-178. I made of the book “Ultimate Study Guide: Foundations Microsoft Project 2010” available from Project Experts (or Amazon). It took about 8 weeks to read the entire book and complete the practice labs. Even if you don’t sit for the test, your knowledge of MS Project will greatly improve.
I scored about 80% or so on each of the test sections. No score is supplied other than a bar chart and 80% is an estimate on my part.
I also have the Project Server book from Project Experts. We call it the “Gold Book of Knowledge”!
