What year would you graduate high school if you were born in 1990?

Typically your graduation year would be in 2008. So I was born August 23 1990. School usually starts towards beginning August. First year of school (Kindergarten) was 1995 through 1996. I graduated May of 2008 at the age of 17. But if you fail any classes and had to retake that class the graduation year will change.
