Keep your papers on a record
A record is a private link that collects your papers, adds up a readiness map across your last ten timed papers, and builds missed rounds from the questions you got wrong. No name, no email: whoever has the link can open it, so keep it to yourself.
Already have one? Open your record link and start papers from there.
Before you start
- The server keeps the time. A paper handed in more than 2 minutes late is still marked, but labelled over time and left out of the readiness map.
- An open paper can be handed in for 24 hours. Papers not kept on a record are deleted after 30 days.
- Works without JavaScript. With it you also get the countdown, flags and the answer sheet.
- Open book is fine. It is practice; nobody is watching.
