It was primarily built to serve as a Scantron replacement, so classroom management features are limited to online testing and course announcements.
Full disclosure: I work a full-time job (at least for now, save for any layoffs) so support would be somewhat limited. I can also take down the paywall for as long as needed for any schools affected by Covid-19
Other free options:
- Moodle (more technically involved, needs to installed/hosted by someone and setup can be challenging)
- Canvas (I haven't personally used this, but it seems to be growing in popularity. From what I understand it is somewhat similar to BlackBoard)
