A few clarifying notes
- Educators get a free account too. A free educator account
includes the same tools as a student account, plus an introductory lesson plan,
worksheet, and quiz. The Educator Pack is an optional one-time upgrade to the
complete classroom library.
- One-time means one-time. The Educator Pack is not a
subscription — you pay once and keep the pack permanently, including every
future addition.
- Cancel Pro any time. Pro is a month-to-month subscription you
can cancel from your account page.
