Take the whole thing for a spin

No sign-up. You get a private classroom of your own, already part-way through week 1 — with three classmates who've turned work in.

• 🎓Start as a student: released lessons, playable SQL games, turn-ins
• 👩‍🏫Switch to the teacher: release a day, read the work, manage the roster
• 🔒Entirely separate from the real class — enforced in the database, not by routing
• 🧹Deletes itself when you leave (24 hours at the outside)

In the class? Sign in to the real course instead — your lessons and turned-in work aren't here.
