We allow teachers to change how exercises are presented to students. To change these settings, click on the "SETTINGS" tab in the "TEACHER" environment.

Go to the section labeled 'Practice mode'. You will see four options.

Options explained:

Exercise by exercise- Students can't skip exercises, they have to do them in order. Once they do an exercise, they can go back to any previously done exercise.

Learn per sequence of exercises- Students can't go back or forth through exercises. Only once they are done with the full sequence can they go back to the beginning and try again.

Learn without restriction- Students can click on any exercise, and go back and forth freely.

Adaptive exercises- Students will first have a diagnostic test that will determine their level in the given section. Exercises will then be adjusted to that level. (see more under Adaptivity).

❗ You will only see these changes if you switch to the Student view. As a Teacher, you can always do exercises without restrictions.


Adaptive systems work by analyzing the performance of the students, and subsequently, choose to make the material harder or easier. In other words, it adapts the path the students take through the content so that it fits their level.

How does adaptivity work?

The student must start with a mandatory diagnostic test on a Chapter level. This test contains the most difficult exercise (based on user statistics) of each topic (package) discussed in the chapter. If students are able to solve this difficult exercise during this test, they have effectively proven that they master the topic (package) the exercise represents. They subsequently receive a 100% progress in the reporting environment on that package. When they are not able to solve the exercise in the test, they will still need to show they master the package during adaptive practice.

What does adaptive practice look like?

An unmastered package of exercises is started in the middle, on an intermediate difficulty. To master an exercise, students need to get a score of at least 60% on that exercise. When mastering an exercise, they move up two steps (+2) in the package. Failing to solve the exercise means students move down the ladder one step at a time (-1). Once an exercise is mastered, the student will not see the exercise again.

To finish a package of exercises, students need to successfully finish one of the last two exercises in the package. The package progress is shown to the student in a progress bar at the top of the screen.

Once a package is mastered, the students get a message. When the package is then restarted, the students get to redo all exercises individually in the non-adaptive mode. To avoid confusion, a message will be shown that the package is already mastered each time the students start a package that is already mastered.

Additional adaptivity options

There are two additional options with which a teacher can control adaptivity:

  • Use diagnostic tests per chapter: There will be one diagnostic test per chapter, and student can do it only once.

  • Students can repeat diagnostic tests: This allows the student to redo the diagnostic Chapter tests any number of times, either on Chapter or on Sub-Chapter level.

  • Chapters are locked until previous chapters are mastered: A student must master preceding chapters before he can continue with the next chapter.
