Great Web 2.0 Online Quiz Creator

Today I found myself looking for an easy way to assess Excel 2007 skills in my 8th grade students and I have to give kudos to ProProfs. What a great quiz maker and web 2.0 tool for educators. Not only did I find a great quiz, it came with embed code and is not sitting on my blog. Thank you ProProfs. Has anyone else had such success? Let me know if you give it a try.
