Hi Dominique
I know, there are so many different applications, one can't always see the point at first glance. For example, the application you just described:
> At the moment, to my knowledge, there is no way to obtain random sets of questions, for example, one student would get questions A-1, A-2, A-3, another student would get questions B-1, B-2, B-3, etc.
IMHO A and B are two different quizzes, as Bret already pointed out - and they are "definite" questions, 1-2-3, not random!
I see, where the complication is:
> For example, one student gets question C and another student question B,
where question C contains sub-questions C1, C2, C3, etc. and question B
contains sub-questions B1, B2, B3, etc.
You want the questions to appear in "sets" - question C is in fact C1, C2 and C3. Agree, you can't get that with randomizations, the question type of C must support sub-questions. As you pointed out, there are such question types like Cloze and Formulas.
But I don't think
OP is thinking of sub-questions. He just entered the quiz forest and looking for regular trees. Only thing he hasn't seen the separation of quizzes and question categories yet - and that quizzes can pick questions from question categories randomly. In short, what he is looking for is basic, it was there since the quiz revamp (somewhere in early 2.x?)
