A free tool that is capable of selecting questions from a pool and shuffle them randomly? I will be conducting exams, and I need a tool that can let me shuffle and select random , small questions from a pre-defined question pool. My questions are typically matched and complete.

It would be ideal if I can export to word after that. Any idea or suggestion is appreciated.
I would recommend to use ClassMarker, which is a great tool for creating a quiz with random questions.

You can choose questions you select and randomize the order of the selected questions, randomize answer options or add randomly selected questions, so each time the quiz is taken, different questions will be pulled from your question pool.

Also, the option of exporting the tests to word is available.
