Thanks for the feedback. The discussions are once a week, and are about an hour (just like most college discussions). The total, one-time price is $25 * (N-2). It is not pay as you go nor a subscription. You can cancel anytime before the third discussion happens for a full refund as stated on the course's page. Apologies that it is unclear. The thesis behind the pricing is for stable planning. Material needs to be prepared in advance every week. Instructors need to be found and trained. Having a variable, unpredictable budget each and every week would hurt the quality of education.
