SD chapter is in SoCal, and it is one of the more competitive ones. Usually it is dominated by Carmel Valley Middle School, but in the last couple years the Nguyen twins (from Black Mountain MS) have taken the top spots. In 2016, the top score was 44 (?) and the countdown cutoff was 39.
At the state competition, the CVMS team placed 1st in 2014, which is one of the only times a SoCal team has done so. In 2014, SD chapter students placed 2nd, 3rd, (incomplete). In 2015, san diego students placed 1st, 3rd, 4th, 6th, 11th, 12th, 16th, 20th, 21st, and 23rd. In 2016: 1st, 2nd, 6th, 9th, 10th, 16th, 19th, 21st, 23rd, and 25th.
San Diego would have sent 1 person to nats last year and 2 this year, but they opted out.
