What is 2157?

The year I finish school. I'm in 8th grade and in my district you only can get held back twice, meaning a maximum of 3 years per grade level. 3x5=15 If you get held back all the time you need to get a G. E. D. Oldest person to ever live was 122 years. Once your dead you can't be in school. 3x5=15+122=137 Current Year: 2020( this year sucks)+137=2157 aka end of school.
