My 3 yrs old baby was promoted to GradeR and she is turning 4 in April. I have complained at her school but they say she learns fast and answers every time and they need to give other kids a chance hence would repeatedly take her to a higher class.

I have concerns because SA schools accept kids who are 7 years to do grade 1, that would mean mine would have to repeat GradeR 3 times. Is there other means to deal with this, schools that cater for fast learners etc.?
