Running 3.5.3+ in a corporate environment.
Scenario: A student is enrolled in a course and takes and passes the exam. At some indeterminate time later, the course and exam are revised/updated.
Desire:
A) I want the updated exam hidden from the students who took and passed a previous revision (this one I figured out).
B) I want previous revision exams available to the student for review if and only if they passed that version exam.
For example, Rev 0 of an exam is taken by numerous students including student S. Later, Rev 1 is issued and students T and so on are enrolled. Student S does not need to see Rev 1 exam but I want him to continue to see Rev 0 (if they so desire) and I do not want student T to see Rev 0 only Rev 1.
For part A, I set the Restriction to not show if that student already has a passing course grade. Specifically, the restriction reads: Not available unless: You do not get certain scores in Course total (hidden otherwise).
However, I am stuck on part B. I could create a new course for each revision, but that will generate a profusion of courses. Plus, students do not always take exams when they are supposed to and I do not want to enroll those who did not take the exam in another course and I want those who have taken it to have access to updated materials. I thought I could use a grade restriction, but the grade restriction does not have that quizzes grade as an option. I guess I could put the passing students in a group and base the restriction off of that, but that complicates things for the teachers. I'd rather have the complication on my side.
The table below summarizes my desires.
| Took Rev 0 | Did not take Rev 0 | Took Rev 1 | Did not take Rev 1 | |
|---|---|---|---|---|
| Rev 0 | See | See (before Rev 1) Not see (after Rev 1) | Not see | Not see |
| Rev 1 | Not see | Not see Rev 0 | See | See (before Rev 2) Not see (after Rev 2) |
| Rev 2 | Not see | Not see Rev 0 or 1 | Not see | See |
Is there a way to do this? If so, how?
Thank you for your assistance.
