Sometimes forgotten, for it is certainly not new or "sexy", yet a powerful quizzing tool to add to your collection of non-LMS Web 2.0 resources. Very, very robust. Allows you to manage classes, quizzes, and reports. Easy to use. Stable (I first started to use it over a decade ago).
Once you create an account, you will see the tabs across the top of the page for instructors.
Susan Oxnevads Blog has some great tools and she provides oodles of well-organized details on the tools she recommends.
In this case she is recommending Flubaroo. A terrific script that a I have used to make Google Forms into a self-grading quiz or test. Not as robust as other tools designed as quizzing tools (Quizstar...), but it works. The only issue I came across was a difficulty in setting up the automated email back to the student with their results. Other than that it works peachilly.
