And they care about the score in context.
For example, if an applicant is coming from an underperforming public school, with high grades and stellar recs, lower SSAT scores are not necessarily a red flag.
One AO at a popular not-so-safety school here commented that they consider it a red flag if an applicant from a more affluent background has low SSAT scores, particularly if the applicant was from an independent school that included SSAT prep in their curriculum.
How a B is viewed is dependent on the course rigor and school reputation, I suspect. I’d be more concerned about the teacher rec - don’t most schools require a rec from the current math teacher? Going to the extra help hours, for example, could help that.
Ultimately, it depends on the type of BS schools that mothermama’s daughter is setting her cap on, and what else is in her application.
