We have a mentor/mentee program that is run by the students. Its completely voluntary. First year students opt in and fill out a survey to be paired with an upperclass student. The 2nd years complete a similar process. There is a committee of 3-4 students that pair the 1st and 2nd years and arrange events. We have an event every semester. Then its mostly a one on one relationship and each relationship is unique. Some people meet up and study together, others email occasionally, others become best friends. Its been a great success for us and I'm really happy being apart of the program.
