The entrance time of 87-year junior college was in 2006 and the graduation time was in 2009. I went to school normally and didn't repeat or skip a grade. My college education is three years. I graduated from junior college in 2009, six years in primary school, three years in junior high school, three years in high school and four years in college. I went to school at the age of seven, 1987 plus 7 plus 6 plus 3 plus 3 equals 2009.
