Evaluation Protocol
The benchmark is designed for single-turn exam-mode evaluation.
Each item is presented once with:
- German problem text,
- five answer choices
A--E, - any question image,
- any image-based answer options.
The model must return either one final answer letter or an explicit abstention token such as Declined.
Scoring follows the original contest rules:
- correct answer:
+points, - wrong answer:
-points / 4, - abstention:
0.
Accuracy treats abstentions as incorrect so that solving performance and abstention policy can be analyzed separately.
Exam-level results should report both raw contest points and normalized percent maximum score:
percent_max = total_points / maximum_possible_points * 100
Evaluation should avoid tool use, retrieval, multi-turn correction, or item revisiting unless explicitly reported as a separate protocol.
