Options

The real thing, not a picture of it. Try it.

01

Ask, don’t fill in a form

Switch the question box to Make and type “20 cards on chapter 3” or “a practice test for Friday”. Pick the files to use with a click or @, or let Amos use what you’ve covered.

02

Tests that mark you

A practice test grades every answer, shows which gaps cleared and which opened, and lets you retake only the ones you missed or turn them into flashcards.

03

Change it by asking

Each one opens beside Ask Amos: say “make these harder” or “fix this card”, undo the last change, or edit it by hand. Keep it private, share it with your class, or send a link.
