I want to set up a quiz where students get different randomly selected problems. All work will be done outside of the moodle quiz and submitted via a single file. Grading will be done manually. I tried to accomplish this with randomized descriptions but now understand that that won't work in moodle. Other people were content with the essay option. But I don't want to provide text boxes, or have students upload separate files for each problem.
A previous response to a similar question (https://moodle.org/mod/forum/discuss.php?d=344523) said that "in places where you just want to randomise a bit of content, there are other ways to do that in Moodle, so there is no need for the quiz to be able to do this."
But how to do that? Please provide links or examples.
