Ditto what everyone has said -you have a very bright daughter with difficulties that may affect how efficiently she takes information in and creates output/ demonstrates her knowledge. I'm not sure if the school did any testing beyond the WISC? But, if you not, you may want to consider a full neuropsychological evaluation. The WISC alone, cannot give you complete insight into her learning profile. It is not unusual for people with score patterns such as your daughters to have challenges/snags in other areas. With more understanding of her needs and strengths, you will have a better time supporting her in a complete and effective way.
