The level of practi-cality of the questions obtained is 96.25%, very practical category. The reliability coefficient of 0.891, reliable. The level of difficulty is known to be 80% of the items in the medium category, 20% of the items in the difficult category. The discriminatory power of the question is known to all items (100%) in good category, meaning that good questions are used to classify the level of stu-dents thinking abilities.
