Build me a online learning platform like coursera

The project’s primary goal is to create a website for instructors across various domains to publish their courses on their own websites. We will be implementing the quizzes (if any question gets correct answer, then we increase the question level), grading a student, showing the report card of the student, when the student leaves the course, his academic progression will be paused where he left, whenever the student he resumes the course, his academic progression will be resumed. The initial effort in this project will be focused on creating the main features which will be limited scoped for the tenure of this course and making it as a running prototype and incrementally adding more features in the future
