Will do - probably looking to upgrade after our school term ends in late May / early June, so I'll test and report back if someone doesn't reply sooner.

So I tested the functionality on Moodle 3.3 and it did not seem to work like it does on Moodle 2.9. When I opened a quiz, it just shows all the questions rather than one at a time like I want, and even shows the final submission screen. Can't seem to get out of it either - the submit button doesn't work. None of the drag and drop questions seemed to load correctly either. So I'll be sticking with Moodle 2.9 for now.

Which theme are you using. I expect it only works with older themes, not Boost.

Ah. I was using Fordson theme with Moodle 3.3, which the author describes as "a child theme of Boost" ... so I guess that's the issue, huh?

Well, certainly worth trying with Clean theme to see if it works.

Hi Tim,

I'm also interested in using that plugin but we are using Moodle 3.2 + 3.3 and even 3.4.
We are using the default theme (design) of Moodle, and didn't change anything visually.

But as Kevin Bleier said, in Moodle 3.3 or 3.4, when module is activated, all the questions show on the same page.
It also makes the quiz impossible to use (offline it doesn't save anything, and online you can't also save replies).

It seems the plugin is incompatible with Moodle 3.1+. Tim, are you thinking updating the plugin to these versions ? Could I help you ?
Or are you thinking not maintaining the plugin anymore.

Thanks

At the moment, the Open University is not using this plugin, so it is not one that is a high priority for us to upgrade.

From the description, it may be as simple as some CSS that needs to be chagned to work with newer Moodle Themes, and this plugin does have pretty thorough automated test coverage, which helps with maintenance.

If anyone else is able to work on fixing this, then that would be great. We could either transfer maintainer-ship of this plugin, or I could merge a pull request into my repo. Thanks.

Hi Tim. As with all the plugins you're involved with and share with the community - many thanks for making the functionality this plugin affords possible. Re. 3.5 compatibility: if possible, please could you quickly confirm that the plugin is fully functioning under this version of Moodle? I know it states 3.5 *is* supported under the versions listing; however, I was just a bit worried re. whether the issues identified in your own and André's comments above have since been resolved. Again, many thanks.

Well, you need to understand that the Open University is not actively using this plugin at the moment, which reduces the amount of real-world testing this plugin gets. However, when this plugin was created, I implemented very thorough automated tests, and those all still pass. They simulate a student attempting a quiz using this plugin, including the tricky edge cases.

If you want any more testing than that, you will need to set up a Moodle 3.5 site for yourself and do some extra testing. If you do that, please report back here so others can benefit from your results.

Hello,
I installed the fQuiz fault-tolerant mode and set up a Quiz to use this mode. All questions are single choice MCQs.
A student had a connection problem and was able to recover a file called 2020-i118245-a28161-d202006161305.attemptdata
I wanted to upload this file to retrieve the student's responses, but I receive this following error message. Could you help me understand why the import didn't work. Do you know how to fix this problem? I have Moodle 3.6.10
Best regards,

Two possibilities I can think of:

1) When time expired, Moodle automatically closed the quiz attempt, and so it is no longer possible to add the responese.
2) The student's internet connection came back, and they were able to submit the responses themself, so they are already processed.

If 1) then it many be possible to undo the effect of the quiz being submitted by editing in the database, but it is not easy. That would require something like MDL-35745.

thank you for your quick response.
I am in case number 1 because the quiz is configured for an automatic sending and certain answers (for questions from 1 to 8) are already recorded for this student.
I can modify the table "mdl_quiz_attempts" and go to the student's attempt. Do I need to change the status from finished to inprogress or other status ?

It's more complex than that, because you also need to update the data about each question (https://docs.moodle.org/dev/Overview_of_the_Moodle_question_engine#Detailed_data_about_an_attempt)

Hello
Indeed, I see that it is not as simple as I imagined.
If I have to manually modify the states of questions 1 to 9 of this attempt, should I make them in which table? Here are the tables that I have identified:

mdl_quiz_attempts
mdl_question_usages
mdl_question_attempts
mdl_question_attempt_steps
mdl_question_attempt_step_data

I just sent you a private message with a link to the student's file
Thanks for your help

Well i have to report your plugins weakness.

Whenever we are attempting to filter our formula using mathjax filter, it failed.
maybe because the plugin meant to be used on non filtered question.
