This paper examines a peer assisted study program that has been operating for several years and which has expanded to be offered in all three core first year subjects of the faculty. The scheme has assisted a large proportion of students from a wide variety of backgrounds to adjust. In all three subjects, those who attend PASS groups regularly have obtained better academic results than other students. Qualitative results have shown improvements in understanding and satisfaction with a friendly informal learning environment. Peer leaders have also gained transferable skills which may be used in further study and in the workforce.
