The document presents an analysis of test items for a Physics exam given to two groups of students, identifying the difficulty level and discrimination value of each item to determine if items were good, fairly good, poor, or inconsistent. Several items were identified as very easy, very difficult, or having very good discrimination between higher and lower performing students. The analysis provides guidance for the teacher on which test items to reuse, reteach, or remove from future exams.
