Reviews that providers cannot buy

We will never accept money from advertisers to remove or bury negative reviews. We spare no expense defending the service from course providers who want a review removed simply because they do not like it.

How rankings work

Powered by the wisdom of the crowd

A large group of ordinary people tends to reach a better aggregate judgement than a single expert. That idea is what makes any review aggregator work, but only with a large data set and a way to filter spam and low-quality reviews. That is why we are relentless about the quantity and quality of reviews: when a course ranks first in its category, it earned that spot on merit, not manipulation.
