Drip content
Drip content releases lessons gradually on a schedule instead of unlocking the whole course at once. Release can be tied to fixed dates or to days since enrolment.
It helps sustain pace and avoids the early binge that ends in abandonment. It also reduces the risk of someone buying, downloading everything and requesting a refund.
The flip side is frustration: a motivated student who wants to move fast hits a wall. Use it where sequence genuinely matters, not as forced retention.
