The school system in India has four levels: lower primary(age 6 to 10), upper primary(11 to 12), high(13 to 15) and higher secondary(17 to 18). The lower primary school is divided into five”standards”, upper primary school into two, high school into three and higher secondary into two. Hopefully this helps you.
