A filtering system:
- One is at the lecture development level, we recruit only those best lectures from our faculty members.
85% of lectures are from professor.
- Two is at the manufacturing level, the Supercourse team filter the lecture before uploading it on the web.
- Three is at the utilization level, the teachers select the best and the most appropriate lectures for the students.

There is also a quality assurance system. Each lecture has a review page at the end of the lecture. And faculty members exchange their comment on the lecture quality via email.
