Patterns of students' time-use can provide important insights into student learning and development in higher education. Previous empirical studies conducted in developed countries do not allow us to generalize findings on time-use patterns for students from countries with different national systems. This paper aims to identify national differences in undergraduate patterns of time-use and their links with the individual characteristics of students. The sample (N = 166,919) was derived from highly selective universities from three countries: the USA, China, and Russia. Significant differences in undergraduate time-use patterns in three countries were observed. In addition, significant interaction effects between national variables and individual characteristics were found. The results allow us to conclude that there are national differences in the power and direction of links between time-use patterns and individual characteristics.
