Hi CarlyMarieTharp :
I'm in the Computer Applications class as well.
The Challenge Assessment for the Computer Applications class allows you to prove to Penn Foster College that you already possess the skills and knowledge that you would otherwise get from the Computer Applications class.
There are two parts to the Assessment: the essay-type questions and the practical exercises. In the exercises you need to create certain documents using the instructions and files provided. If the instructions are unclear, it is best that you take the course rather than taking the Assessment.
The course teaches some advanced techniques for Word, Excel and PowerPoint and although I am ranked at the Intermediate Level at work (read: I know more than everyone-but-the-IT-staff) I am taking the course in order to learn more.
