Try to break the marker

The fastest path

Open Zayeed in this browser

Nothing to install and nothing to sign up for. Create a short-answer item, and set an accepted answer with a synonym group. Then try each of these in the tester beside the editor:

• The right answer with the wrong case.
• The right answer with a doubled space.
• A British and an American spelling of the same word.
• A formula with and without subscripts, once with the subscript marked as required and once not.
• A one-character typo in a long word, at each leniency setting.
• Three of five reasons where the item asked for three.

Each result shows the mark and the reason: which synonym matched, which tolerance stage let it through, and what the arithmetic was. That is the thing worth judging.

Then take it offline

1. Turn the network off entirely.
2. Sit the paper. Answer some of it, close the tab, reopen it and carry on.
3. Submit. The mark appears immediately — it was computed on the device.
4. Turn the network back on and watch the attempt reconcile.

Then take it to a second device

Sign in on a phone, choose Show a pairing code on the first device, and type the six digits. The same items, results and settings appear. Sit the same paper on the phone and confirm you get the same mark, including on a paper whose script the phone has no input method for — that is what the pack's on-screen keyboard is for.
