Are Viafocus lessons free?

Yes — every lesson in the library is free to play in the browser, with no account required. A free account lets you save lessons and see results.

Can I run a lesson live with my class?

Yes. Start a live session from any lesson — students join with a code on their own devices, and their answers land on your dashboard in real time.
