We compare 967 online courses from 10 providers. If something on a page looks wrong, or the course you want is not listed, tell us — corrections are the fastest way this catalogue gets better.
Two things we get asked a lot, answered here so you do not have to wait for a reply:
We do not sell courses and we cannot enrol you. Enrolment, payment, refunds, certificates and course support are all handled by the provider — Coursera, Udemy, edX and the rest. The Enroll button on a course page takes you to that provider's own page, which is where those questions have to go.
How we choose and rank what is listed is written up in full, including where the data comes from and how the site is funded, on our methodology page.
