My daughter is 13 years this year and has been through them - they too had booster classes and extra leassons to help any children who needed it - the school was really good with the children - My daughter is now in High School and is glad she did those SATS now as its helped her to better understand what standard of work is expected of her - shes blossomed since the SATS - she was a little worried while doing them but teacher support aswell as support from home helped her
