Players can score up to 1000 points in each lesson.
Each lesson is composed by exercises. The lesson maximum score is divided by the exercises amount equally.
If there's 10 exercises in a lesson, each exercise in this particular lesson is worth 100 points, since 1000 points (all lessons are worth 1000 points) divided by 10 exercises = 100 points.
However, to be able to achieve the exercise's maximum score, it is necessary to complete the exercise correctly faster than 50% of its total time.
Answering the exercise correctly after 50% of the total time has passed will decrease your score as the time goes by! The longer it takes, the lower your score!
