Some (but not all) lessons have additional information that provide a closer look at the subject matter. You can tell which lessons have this additional information when you see the small “i” button at the top of the Current lesson tab. If you’ve mastered a lesson, but want to view the information again:
- Go to the Mastered Lesson tab.
- Tap the filter icon in the upper-left corner.
- Tap the lesson you want to review.
- Tap the “i” button at the top.
