Which English channel to start with

Ranked by median difficulty, easiest first. The bar is a range, not a label — a channel typically spans a wide stretch of the scale, so one level would be false for its own hardest videos.

6 of these 7 channels carry the same vocabulary band (B1-B2), and their scores still run from 0 to 88. That gap is pace: what separates the easiest of these channels from the hardest is how fast people talk, not which words they use. How that is measured →
