Looking for a quiz platform - white labelled / code

Job ID: 40185681

Budget: ₹37,500 – ₹75,000 INR

I am looking at a Quiz platform - preferably with white labelled:

This is the most important feature.
There will be 2 formats of quizzes.

1/ Quiz after every lesson of the course
2/ Weekly quiz

All quizzes need randomization of questions.
Example: Every quiz will have a pool of questions – say a 100 questions. When a student takes a quiz for the first time, there will be a set of 20 questions that will form the quiz. If the same student decides to take the quiz again, a random set of another 20 questions could get asked.

Quizzes to be only MCQ or ‘True/False’ formats.

Scoring and Leaderboards:
All quizzes played will get ‘points’. There will be a scoring mechanism that will result in points won for each question answered correctly in the quizzes.
