How this works
Nothing here is gated and nothing is new: every step is a page or a calculator already on the site, and you can jump straight to any of them. The order is the contribution, along with the last step — a round of Grade the Claim, because reading something and being able to judge it later are different skills, and only the second one survives the week.
Ticks are saved on this device. Claims you meet in the check come back on a spacing schedule, and what you know keeps the tally.
