Qengine is a quiz engine. Write one question for it, and it can generate randomized versions of the same question. This makes writing quizzes much easier and helps prevent students from cheating.
Qengine is a framework for delivering quizzes that use powerful back-end tools, such as SageMath, to generate content. It currently works with Moodle and will be supported on other LMS platforms in the future. It's also open source. If you're interested in developing features or extensions to Qengine, please visit the Github repo: Qengine Repo
