Dripping content based on completion of the previous lesson. A student benefits from knowing 1. the admin is paying attention 2. The student is encouraged and acknowledged after lesson completion 3. students receive relevant and timely emails based on their interaction. In our course dripping content after 7 days etc the student is receiving email for lessons later they are not close to. And yes we have a quiz at the end of each lesson. This feature is a must and obvious feature for high interactive engagement in a true funnel automation for courses. Get er done!!!! AND a bigger better version of this is they get dripped the next lesson and new email after the previous lesson is completed vs. only having the option to drip the lesson at random times that take no consideration for the pace each student takes - it is all mismatched and loses the personal touch. NURTURE NURTURE NURTURE based on real life scenarios - not one shoe fits all. ;-).
