Should the score be shown immediately?

Hi!
I am creating a test project named Objectif-Brevet.fr (I’m french, yes :sob:). I would like to create a simple way to review school courses, with simple exercices.

For example, I created this beginning of exercice page, for work Geography of the France.

There are 13 regions in France, so I would like to ask 13 questions (“Sélectionnez la région Occitanie” => “Select Occitanie”).

My first question is : Should I progress the exercise by changing pages each time (one page per question), or should I progress the exercise in a single page, using JS?

And my second question is : Should I show the score (number of correct answers) during the exercice or after ?

Ok, so I don’t know if you understand me when I write (hehe French), and I don’t know if this forum can answer to my questions ?

Thank you to those who will take the time to answer me!
