At the moment, when building a quiz, you can add
1. Specific questions.
2. Questions picked at random from a given category.
3. Questions with internal randomisation (e.g. calculated).
4. And calculated questions can even have the dataset values synchronised, so if Q1 asks you to calculate 42 + 73, then Q2 asks you to calculate 42 * 73.

But, what you can't do is have Q1 selected at random, but then Q2 and Q3 chosen to match Q1.

For example you might want students to get one of these three sets of questions as the first three questions in a quiz:

Variant 1:
Q1 Which Moodle activity would you use for asynchronous discussion:

• Quiz
• Forum
• Resource

Q2 Forums can be graded? True / False
Q3 Forums can be used for social contstructionist learning? True / False

Variant 2:
Q1 Which Moodle activity would you use to provide a document for students to read:

• Quiz
• Forum
• Resource

Q2 Resources can be graded? True / False
Q3 Resources work well for social contstructionist learning? True / False

Variant 3:
Q1 Which Moodle activity would you use to automatically grade students:

• Quiz
• Forum
• Resource

Q2 Quizzes can be graded? True / False
Q3 Quizzes can be used for social constructionist learning? True / False
