Your remote. This slide and the next, your notes, the clock, and every answer with its nickname.

Before your first class

Do students need an account or an app?
No. Students go to elenqos.com/join on any phone, tablet or laptop, type the class code and pick a nickname. Only teachers sign in.
Which files can I upload?
PowerPoint (.pptx or .ppt), OpenDocument (.odp) and PDF, up to 50 MB and 300 slides. PowerPoint speaker notes come along to your remote.
What if the Wi-Fi drops?
Each screen says it’s reconnecting, then jumps to the slide you’re on. Answers given meanwhile arrive once it’s back, and a reloaded projector keeps its place.
Who can see my presentations?
Only you can edit or present them: the projector and the remote open only for the class’s teacher. Students see the slides while you present, never your notes or answer keys.

Bring the deck you're teaching tomorrow.
