Suppose business college A first debuted in 2000. It opened its first business course in 2000, and the course will finish in 2004. In 2001 it opened a second course, and students who enrolled in 2001 will graduate in 2005.
What should we call the students who graduated in 2004? Can I say “a first generation of business graduates in college A”, or is there any better term?
Of course, the students who graduated in 2005 are not the first generation of business graduates in college A.
