Current Exam Pass Rate: 70%

As a long time APICS Member who is CPIM and CSCP certified and also teaches CPIM certification classes, I am no stranger to tests, self study and online learning systems.  I have to say that the DDLP exam was one of the best practical application exams I have ever taken.  The whole idea of having spreadsheets ready to be used and reference materials readily available really does simulate real life where you would apply your knowledge to develop real life solutions in my opinion.  I also very much enjoyed the online classes and the practice exam.  Well done Demand Driven Institute.
