9th, 10th, 11th and 12th grade

[Mateo2912]

In the U.S., high school goes from 9th grade until 12th grade. In my school (in Colombia), High School goes from 9th grade to 11th grade, with no 12th grade whatsoever. My school has Elementary school, Primary School, Middle School and High School sections. I entered my school in 7th grade. Should I submit my date of entry as the date when I started 7th grade or High School (9th grade)? When sending reports, does the fact that my High school has 3 grades (9th, 10th and 11th) affect anything? Should my counselor only send the transcripts for 9th, 10th and 11th grade or should he also include the transcript from 8th grade (Middle School)? I’m currently coursing 11th grade (my senior year)
