The project involved senior students working with first year students over the first semester. Evaluation showed that according to the students' perceptions cross year collaborative work was a positive experience. The first year students felt that they gained a better understanding of university life and at the same time felt that their English skills of listening, speaking, reading and writing had improved. The senior students found the experience very rewarding because the interaction and the task were invaluable in their understanding of issues in English language learning.
