What year did you start high school if graduated in 2005?

To determine the year someone started high school if they graduated in 2005, we need to know the typical duration of high school. In most countries, high school lasts for four years.

Counting backward from the graduation year, we can calculate the year the person started high school:

Graduation Year: 2005

Years of High School: 4

Starting Year = Graduation Year - Years of High School

Starting Year = 2005 - 4

Starting Year = 2001

Therefore, the person likely started high school in the year 2001.
