Question on quiz Module and my own module

Hy everybody, I'm a beginner in the world of drupal and Opigno. Currently, I work with Drupal 7 and Opigno 1.44. For my internship, I need to create a module that gets the result of each question during the quiz and the final result. So, I identify the module whose name is "quiz". My problem is, I don't succeed to get values. When I use the quiz functions, I don't have a good result. When I try to get the result with MySQL request, this request was executed before the execution of the "quiz" module functions. So I would like to know if there is another solution to get these values? Thank's.
