How to interact with a bank of questions ?

Hello everybody,

Here is my problem.

I am currently working on a project to develop a "smart quiz" on Storyline 3.

This quiz would work in 2 steps.

First step: Quiz 1 that will draw randomly questions from 3 different bank of questions (theme 1, 2 and 3) and provide a page of results where the score of each theme will be displayed

Second step: Quiz 2 that will push questions from the same banks of questions but according to the results of each theme on the first quiz.

Ex. If in the first quiz, the user had 80% of success on the theme 1, 10% on the theme 2 and 30% on the theme 3 - in the Quiz 2, he will get more questions on theme 2 and 3.

I already manage to develop the first step.

But how can I do the second step ? Is it possible to interact with the bank of questions with JavaScript ? or with variables ?

Thanks a lot for your help !
