This question is a following of the two clever and efficient answers linked below to elaborate semi-interactive quizzes/MCQ with ocgx2 (OCG/OCMG).
(1) ocgx2: verify and reset of Multiple Choice Questions with OCGs
The next step I want to deal with is to allow automatically three trials to the user each time he/she click on the check button (see the layout of the result without cosmetics). At the third step, the points are assigned. For the moment being, I am able to on one hand, have the correct/wrong quiz proposals with the OCMD layers, and on the other hand, a set of three symbols related to the trial number (OCG layers). The idea is to mix the two orientations.
After many tests, with nested or not environments, I must admit that I am lost... I certainly don't understand everything about the power of OCG/OCMG. Therefore, is this approach feasible? Intuitively I think so but if yes, how to solve such an issue?
I am also aware of the PDF viewers limitations:
(3) Tikz & OCG: make button cycling through different layers
I do hope that the new (2019) OCMD layers for LaTeX could be a friend...
