How to use

Select a question generator from the menu, then enter a generation key - or generate a random key if you don't have one. A question will be generated on the fly from the information contained in the key. The same key will always generate the same question. You can submit your response to see the correct answer together with an explanation.

Question generators are a key feature of the OpenTesting framework. They take a string called a key as input and generate a different question for each key. Internally, they make heavy use of OpenTesting's engine and its underlying key-based generation mechanism to add variation to a common question pattern. As a result, a typical question generator can generate thousands of deceivingly similar questions with different correct answers - sometimes even opposite ones.
