How do I pay?
Payment is by bank transfer for now. I send the account details in the chat; after the transfer you send the receipt and your email address.
How do I watch after paying, and for how long?
You receive an invitation by email and watch every session of the course through Loom on any device. The subscription is valid until the end of the semester you enroll in, about 5 months of access to every session, and every new session recorded during the semester is added at no extra cost.
When is access activated?
I add you to the course sessions in Loom, usually the same day.
What about courses still being recorded?
This course is being recorded session by session during the semester and will be complete by its end, once the whole syllabus is covered. The price shown is the full course price and will not rise when it is complete: you pay once, and every new session reaches you at no extra cost.
Are there refunds?
Because full trial lectures are available before you buy, there are no refunds once access is activated.
Is there a certificate?
No certificate is issued. These are recorded explanations of university courses, not accredited training programs.
