Testmoz is a test generator that features 4 question types, automatic grading, a really simple interface and detailed reports. It is free, really easy to use, you don't have to register, no ads, banners, or popups, which makes it great for K-12. You can also password protect your test Each test you create comes with its own web address(URL). You can create true/false, multiple choice, multiple response, and fill in the blank questions. Reporting allows you to see the scores, averages and actual responses to questions. Try it and see how easy it really is! My guess is you will use it again and again.
