Hello Student

Generally in education policy rules for education for all, student should have take admission in class 5 at the year of 10 + years. Naturally taking admission in class 6 the student should have the age of 11+ years  of age. As your son born 25th January 2011 so your son is eligible for taking admission in the class of 6 of any medium of any word in India. Your she should not take admission at the age of 7 in the year of 2022 because he is or her age will not match with the criteria for taking admission in class 7 of any board or any media of instruction in India.

Hope this helps.
