Facebook: Class Year. What does this actually mean?

I first went to my college in 2000. My last year was 2005. What is my class year?





(there is also the added confusion that my college was also my school, so i left in 2005 came back and left again in 2007.)








My question is is my class year the year i joined or the year i left?

It is the year you left (2005).
Reply:Its the year that you left/graduated
Reply:The yr. you left.
