As a web designer teaching at Wake Tech Community College, I have a good knowledge of web design. Comprehensive, I would say, but only insofar as HTML, CSS, and Flash development are concerned. As part of my WEB140 Web Development Tools course, I challenged my students to take this certification. In this way, I could validate the experiences and understanding of the students through demonstration outside of the classroom. I too recently took this exam so that I can practice what I preach. Thank you BrainBench!
