Hello,
React quizzes is in development mode. it's a beta version. I understand the problem.
it is as simple as calculating a simple percentage for the overall quiz:
Percentage = (Value ⁄ Total Value) × 100
there are other question types in which it considers the probability of correct answer percentage.
for example, there is a question type of checkbox type in which there are 3 correct answers. if users mark 2 checkboxes and they are correct. then it will get the fractional percentage.
Show Checkboxes
I want you to have patience, I will notify the development team for better clarifications.
