One other quick point, there are a few schools that require you to send ALL SAT scores from every test date, for example, Colgate. I would look into the schools she is considering and see if they are one of those schools. I would spend some time considering how score fluctuations can impact an admissions decision if she needs a third time and the school wants to see all scores. You can’t predict the difficulty of a particular exam and corresponding “curve” so I would make sure she was as best prepared as possible for both sections.
