While learning how to program using online judges, students should be presented to questions in an increasingly difficult level. Besides, randomized exams should be fair. This work presents a method to classify the difficulty of programming questions based on metrics extracted from instructor’s solution code. This work analysed 354 questions in Python and used in some Introduction to Programming (CS1) classes taught from 2017 to 2019. It was found that the use of metrics extracted from code can indeed be used to estimate the difficulty of questions, in addition to elucidating some aspects of the difficulty encountered by students.
