Competence: the ability to solve the task
This section might be divided into two parts. ‘Pre-skills’ show ability without any need for support. ‘Gain’ shows what was learnt during the task. The awarding of the badges is based on this score. This is the score that is reported back to Google Classroom. 

Efficiency: how efficient the solution method was
There might be a quicker solution with different routes or usage of keyboard shortcuts.
