Thanks for the comment. There are a few things to consider here. Large core courses are often very scalable - it's not a decision of offering them or not, but usually how many TAs are needed to accommodate the final size. If a university would like to increase the number of students enrolled, as long as the main lecture hall can fit additional students, enrolling more can usually be done. Another factor is that a main group that we'd like to serve are students who've had to dropout of school. For this group, they would be most interested in the next level of courses that are more specialized and are less likely to be highly subscribed.
In the end, we feel that creating this new channel into universities will provide value for the students and the universities themselves. If it does, we're confident the administrative procedures are solvable.
Thanks for the supportive note. After passing this stage, we're excited to take our idea to the next level.
We certainly hope it will be disruptive - by opening up quality universities to a broader population that previously didn't have access. We appreciate your support!
