In this study, we fixed the total amount of distinct multiple-choice questions (MCQ) that a student could practice. A simple learning management system called QuizIT was used to send out MCQ practices and analyze students’ practice strategies from the log file of the system.

• Collection of data started after students completed their midterms exam and stopped one week before the final exam.
• Study lasted 45 days, hence being 45 questions. One question per day.
• 7 out of 45 questions asked students to select the output of a small piece of code.
• Remaining 38 questions aimed to help students in recalling the basic concepts taught in the class.
• Students could practice the same question multiple times.
• Students did not need to answer the assigned question every day as long as they finished all the questions by the end of the study.
