Coaching fails in the week after the lesson, when nothing happens. Give students drills instead of homework they will not do, see exactly who practised, and earn a share on every student who signs up.
The reason lessons do not stick is that nothing reinforces them until the next one. 17 timed drills are the in-between: you point a student at their leak, and per-module accuracy shows you next week whether they actually trained it.

Rebuild any hand into an animated replay and review it together, with your logo on the table. Playback fills the screen, so it holds up in a lesson or over a screen share.

Every student who subscribes through your link pays you 20% of their subscription, every month they stay. Fifteen students on Pro is roughly £30 a month back, for recommending the thing that makes your lessons stick.
