A passing grade without sufficient knowledge? The new grading system

Under the new grading mechanism for 9th-grade science exams, a student can receive up to 8 out of 20 points simply for participating in group work.

This assessment approach raises questions: how are the points calculated, what weight do a student's individual knowledge and project results carry, and how is fairness in grading ensured?

Does the new system encourage the practical application of knowledge, or does it make it possible to get a passing grade without demonstrating an adequate level of subject knowledge?
