I'd like to be able to set up an online class where access to certain topics/assessments is blocked until assessments etc have been completed. For example, In the topics section you have materials/videos etc for different units (1,2,3 etc) but access to the following unit is not given until the student has completed all of the assessments/assignments from the prvious unit. For a student to access the resources etc for unit 2, they first must score 80% or higher on each assessment of unit 1. This would help greatly in creating self paced courses on Blackbaud.
