Advanced Adaptive Release allows you to create Rules. A Rule is a set of criteria that determines the visibility of content to users.
You can create a single rule that has to match multiple criteria (AND). For example: Rule 1 criteria is as follows - Homework 2 grade is less than or equal to 70% AND membership belongs to 2 specific groups.
You can also create a rule with a single criteria and combine rules (OR). For example: Rule 2 Homework 8 grade is less than or equal to 50% OR Rule 3 Homework 9 grade is less than or equal to 50%.
