This free offer for closed schools is no longer in effect.
Well, for a while, practically all schools were closed, and verification was pretty simple, but then after a while they were opening and closing week-by-week, and verification of closed status became impractically difficult and time-consuming.
In addition, we’ve made a Basic version of Classwork Zoom free for everyone, regardless of the status of their school. At this time, any teacher in the world can build a timeline for one student at a time at absolutely no cost to them. If you’re interested to compare features between this and the Premium version, feel free, but we’re happy to know that the Basic version will satisfy the needs of many teachers.
