Doing it twice and hearing it twice helped her retain more.
It certainly doesn't work for everyone... who has time to listen to lectures twice, especially when under a full course load? I can see the value, and I have no doubt it is very effective for retention, but I don't think that solution is going to work unless you have a severely limited social life, or are taking classes part-time.
There is a popular business model that takes advantage of such persons. First, get the user hooked on free content, then milk their addiction by offering plenty of goodies for purchase that can 'enhance' their experience, or allow them to show off to their friends. There are many MMO's such as Perfect World that offer the game for free, but encourage the user to buy items that grant a competitive or cosmetic edge in-game. Similarly, the online TV-series Pure Pwnage offers episode downloads for free, but has a number of related accessories available at its 'noobstore'.
