Many universities offer courses supplemented with online activities. Little attention, however, was given to assessing students' preparedness to engage in online learning. This study aims to investigate students' e-learning competencies. Online collaborative learning requires skills and attitudes of its own compared with face-To-face. The study was conducted at the Linear Algebra Course, Faculty of Computer Science, Universitas Indonesia. Fifty-six freshmen students in the second semester participate in the study. Three sources of data were used, including questionnaires, discussion transcripts, and in-depth survey. The results indicate that the students have a good technological competency, have moderate competency in interaction with learning content, and lack of interaction skills with their learning community. A recommendation to improve students' preparedness in online collaborative learning is presented.
