The main restriction of the Quiz fault-tolerant mode plugin ↗ is that the question behaviour must be set to "Deferred feedback", which does not mean that only essay questions are supported. Although I couldn't find a mention in the documentation, I think the plugin supports most of the core question types. Note that the last version of the plugin dates from November 2019.
Moodle Desktop ↗ is no longer maintained since May 2021. My understanding is that the Moodle app ↗ and its offline features ↗ now only support Android and iOS, although the documentation mentions Synchronisation on Desktop ↗.
An interesting note about the offline features of the Moodle app is that we are told ↗:
...we think the Internet is everywhere, but we usually forget about:
One of the most powerful features of the Moodle app is that it enables us to work offline.
- Underdeveloped and developing countries
- Rural areas in big countries
- Kids with restricted data plans
- Shared internet connection in schools/classrooms
and, on the same page, we are offered paid Moodle App Plans ↗.
The bottom line is this. If you are from an underdeveloped or developing country, a rural area in a large country, if you are a child with a restricted data plan, if your school/classroom can only afford a shared internet connection, in other words, if you are disadvantaged and poor, you will have to settle for the basic version, whereas if you are rich and can afford to pay, you have access to better features.
Is this Moodle's new policy? Have you thought about this well? Are those paid plans fair? Are they the best way to get those who can to pay their fair share? No.
When it comes to aid and solidarity, those who have to pay are the richest, period. Not those who would get more privileges in return.
I have always feared the day when Moodle would become a commercial enterprise, worse an unscrupulous business. Has that day come?
