In Florida, middle school has a 1600, no 3200. We also have a sprint medley relay 100, 100, 200 & 400.
Back in my day junior high was 7th, 8th & 9th. Some educator decided 14 year old girls should be in school with 18 year old boys and created the middle school system - 6th, 7th & 8th grade.
Just my 2 cents....
