The Primavera application is a sophisticated software application with many, many features. Not all of the features are taught in the classes. It is simply impossible. Also, the permutations of different calendars, durations, resources and other features can may require a review, especially if you are taking the class to change careers and do not have immediate access to the software. We understand, and we allow former students to sit in the class again on a space available basis. Our goal is to help you understand the application and put it to use.
