## Classes

Classes in Flint can be **classes, clubs, or other organizations.**

Classes in Flint can be made by anyone for anyone. Whoever makes the class becomes an owner of the class. [( _Find more on the distinction between owners and members here_.)](https://help.flintk12.com/en/articles/9049613-owners-and-members-in-flint)

An owner of a class can add new owners and members to the class, create activities, and view all activity sessions that are created by members.

A member can view **open** classes and activities within the class, or **private** and **unlisted** classes if they made them or were invited to them.

## Activities

Activities are AI-powered learning activities that can act as **assistants, assignments, practice buddies, or more.** Some possible use cases for activities include:

- Assess students' understanding of a new topic and give an overview of who knows what  
- Practice speaking 1-on-1 in any language  
- Help students with extra learning (24/7 study sessions before a test)  
- Give students immediate feedback on their writing

Every member of a class can see and interact with:

- Open activities in the class  
- Unlisted activities they are invited to or given the link to  
- Private activities they are invited to

## Sessions

A session is a single instance or interaction that a member has with an activity. A given member can have multiple sessions with an activity, unless the activity's owner sets a deadline or time restriction.
