This article adds to a growing body of literature on how various types of social relations can work synergistically to promote students’ academic success. Students’ study-related social networks afect academic outcome in higher education. The network literature in education generally explores students’ various relations separately, rather than their multiplex relations or when individuals share several relations. This approach risks missing the full complexity of the student experience. The aim of the present study is to add to the discussion on student social networks and attainment in higher education by further exploring multiplex relations maintained in a specifc study program, in which a large share of students in the cohort commute. A survey was distributed to students in one cohort (n=146). The fndings revealed that, in this cohort, students’ friendship, working and learning networks overlap substantially, and that centrality in the friendship and in the student multiplex networks was positively and signifcantly related to academic outcome, whereas centrality in the working and learning networks was not. Points for future research are suggested, and practical implications for those supporting student learning in higher education are discussed.
