BrightCourse is a subscription-based service, so the cost depends on what you choose to license during registration. The first month is FREE when you sign up at BrightCourse.com, which allows you to try the program for a month without cost or obligation.
Subscriptions are based on concurrent stream counts. This means a single subscription can be used by multiple users (see below) as long as videos are not being streamed from the same pack at the same time. In addition, classroom viewing rights are included, and the worksheets can be duplicated and shared as often as needed.
