How Do I Add More Seats to a Classroom?
If your class grows after you've already created the classroom, open its settings and use Add seats. Enter how many additional students you need room for and complete payment — the classroom's seat count increases as soon as payment succeeds.
Step: Add seats
Additional seats cost $7 each — more than the $5 initial-purchase price, since they're a one-off top-up rather than the semester-long batch. Like the initial purchase, it's a one-time charge, not a subscription.
You can only add seats to an active classroom. Once the semester ends and the classroom archives, seats can no longer be purchased — see What Happens When a Classroom's Semester Ends?.
