The aim of this paper is to assess the usefulness of Kahoot! as a formative assessment tool ?in making learning more enjoyable and in understanding the content of an abstract subject (econometrics); in addition to that, Kahoot! was used for collecting feedback. The study was conducted at the Bucharest University of Economic Studies on undergraduate second year students during the academic year 2019-2020. The results show that most of the students associate econometrics with statistics (followed by maths), and think Kahoot! makes learning more fun, though when asked to state which activities helped them most in understanding the content, a large majority perceived exercises and writing on the blackboard as most useful. Moreover, the study reveals that most of the students want to enjoy a course and they love integrating technology within it; as to the integration of Kahoot! within the course, most of them stated that Kahoot! should be played at the end of each lesson.
