Taking twice is fine. Schools know the nature of tests and they will be able to see your child's all scores. Do not be afraid of telling your child true scores. Rather try to help your child to get the best scores based on his or her ability. Please remember that SSAT score is only one of several admission criteria. There are always some other evidences that you might inform that your child is special to the schools other than SSAT score. Please find and work on this aspect as well.。
