randomization under categories

[datamove]

Dear all,

Thanks for the package. I have found it easy to get started and features are greate.

I'd like to clarify how randomization within a category works. the README says

After selecting a larger pool of questions, a quiz can be set to show a random subset rather than all within the pool

On a quiz admin page I can see a drop down menu to select a category, and then a max questions field to set.

It seems to me that max question number is drawn from both categories at the same time. What is the purpose of the drop down to select the category?

Also, consider the following use case: I have a pool of questions with two categories and I'd like to draw N questions from one category and M questions from the other. Is there a way to do it? I could settle to the same number of questions in each category.

Also, how easy is to place all questions on the same page?

Thanks in advance!
