Human: What is the difference between an alumnus and a graduate? Assistant: 
The main difference between an alumnus and a graduate is that alumni are former students, while graduates are those who have completed their education. Alumni can include both undergraduate and postgraduate students, whereas graduates only refer to those who have finished their studies at the college or university level. Additionally, alumni often receive benefits such as discounts on tuition fees and access to alumni networks, which graduates may not be privy to.
