One minute of Quill, in every course
Pick a course and let Quill explain it.
Every unit is a short series of videos, one idea at a time, each under 3 minutes. Quill reads it aloud with a man’s voice, stops for quick checks with a thinking timer, and gives you a strategy you can use on test day. In the eight language courses he speaks the language aloud too, on devices that have a voice for it.
