When you are in the lesson module (exercises, vocabulary, communication, reading, audio, etc.), you will see a horizontal numbered list. Each number corresponds to an exercise and will be highlighted in 1 of 4 background colours:
- white: you have not yet completed this exercise. (4)
- dark grey: exercise currently in progress (not yet completed)(3)
- green: you have completed this exercise correctly (> 70% accuracy)(1)
- red: you have completed this exercise with errors (< 70% accuracy)(2)
Exercises in red (those completed with less than 70% accuracy) can be redone to improve your result and learn from past mistakes.
If you want to do the exercises again, they will be re-evaluated so that you will be able to improve your results where required.
