Field notes
The page describes six printable PDF formats and says teachers can choose 20, 50 or 100 questions with four or five answer choices. It also presents roster-based results, score distributions and per-question item analysis. Markatron attributes its scanning to on-device OpenCV; the supplied extract does not independently test that claim.
