Students pick a date and period, then click Start Lab. No names, passwords, emails, or accounts — ever.
Readings, vocab, questions, matching games, data tables, and a quiz. Progress silently auto-saves to the student's own browser.
At the end, each student sees their grade plus a unique code like 47829-FALCON. They write their name on the printable page.
Student prints or saves the PDF and submits it to the teacher. The code proves authenticity — the teacher is the only person who ever sees the work.
