If your daughter is looking at several top boarding schools, given that situation, she might have some difficulties to get in. I also think that focusing on SSAT while giving up TOEFL would give some advantages. I recommend you to do more active research on possible schools and requirements of those schools.
如果你的女兒目標(biāo)是頂尖寄宿學(xué)校，鑒于這種情況，可能有一些困難，我認(rèn)為重點(diǎn)放在SSAT，而放棄托福將會(huì)有一定的優(yōu)勢(shì)。我建議你對(duì)候選學(xué)校做更多積極研究，搞清學(xué)校的要求。
Here is my suggestion. Children have good and bad days, depending on their mood. Sometimes they will do better at a test and sometimes not as good. I suggestion is that if you can, take as many tests as possible. You can choose the test with the best result to send to the schools. So register for all of them, even if your child doesn't have time to study and prepare. Plus, the more your child takes these tests, the more adept he/she will be, and the scores may be better.
One more thing, there are many good boarding schools in the States that will take a students with TOEFL scores in the 80s range. However, they will also need to look at SSAT scores, grades, comments, extracurricular activities and the essays.
