Is there any extension or tool for dynamic quiz/exam/survey generation

maybe to better formulate my quesiton, the number of questions is unknown (as long as they meet the criteria) so they need to be generated dynamiclly. Though the example is somewhat relevant, it is quite different. The main difference will be dynamic generation of components. I am not sure the dynamiccomponent extension can generate radio buttons (for multiple choices).

You need some way to generate right and wrong answers to questions.

That requires some corpus of knowledge (math, geography, history, food, biology) and some way of identifying plausible alternatives.

The current reincarnation of the quiz show You Bet Your Life (no, not the Squid Games) might give you ideas for how plausible multiple choice answers would be generated.

I do not need to worry about righ tor wrong answer, let's say it's a survey.

This is starting to sound like a Test Data Generator

i would say very similar to a test generator from an existing database, not data generator, but need to do it in App Inventor

Selection of random items from multiple lists is very straightforward.

I reiterate,

Not everything that is calculated needs to be stored.
Not everything that is stored need to be selected.
Not everything that is selected needs to be displayed.
Not everything that is displayed needs to be read.

Selection is not much of an issue, I can inquire the mysql db with certain conditions to retrieve entries. The tricky part is to display them with dynamic components (particularly radiobuttons)

A small sliding window into a long list can be simple and convenient.
You probably encounter them online.

Sounds a good idea to replace radiobuttons with listpicker for choices, now the cumbersome part is to display components dynamiclly. Not complete solution yet, but give you a :heartpulse:

what is missing in the example is to read the questions and answers from the database...

Aside from your firm belief that every photo needs a frame for it, there is the question of how to track the questions and answer choices in your database.

Your app sounds like your own version of Google Forms, which allows users to define their own forms and let other users enter data into those forms that would end up as rows in that Form's Google Sheet.

A Google Form is a form of schema, which you can represent in a dictionary.

also the components are not created dynamiclly in the example.

what is that? also i don't think what i am trying to make is sth very similar to google form

Will Mit punya's survey component do the work? :thinking:

Well, it is always one question and 4 possible answers to choose from...
Why do you think, you need something dynamic for that?

the number of test questions are not certain because as long as the questions in db meet certain criteria, all questions should be retrieved. Also the number of choices for each question are not always the same (this is intentional, sorry that this is not reflected in my question, cannot edit it anymore).

can you share a link please?

here is what i can think of using listpicker for the choices, please share your thoughts.

Even if the block will generate test questions as i hoped, but how can i respond to click of a submit button for a specific question?

apparently, Im not alone here, see this post by Ayun_Challymalang

Click event on a Button created with DynamicComponents

There's no solution for that post yet. Hope some smart cookie can help us here? Thanks
