Students tend to procrastinate. In particular, Computer Science students tend to reduce the number of hours devoted to study concepts after class. In this paper, a case study on the use of Blended Learning to encourage Computer Science students to study is described. Furthermore, an experiment in which the reaction of 131 Computer Science university students to the proposal is analyzed. The material for the preparation of an exam was produced both in electronic and paper formats. 64 students were asked to study using a free-text scoring system, and 67 students were asked to study with printed documentation in the same class. The students' reactions, the results of a pre-post-test and the answers to a voluntary and anonymous satisfaction questionnaire were registered. After that, students were given the option to keep studying with the scoring system or with the printed documentation. 99% of the students chose to study with the computer, and a higher frequency of study was registered during the previous month to the exam.
