chance me at Ivys and MIT, Stanford

Now there is one more question.
Since her SAT score is 1520 and it is in the middle 50% of the accepted sutudents at most of the T20 schools, does she need to take SAT again to push her score close to 75%. Now she may not be able to take SAT again because of COVID-19 situation.
Other part of her appliaction looks good, I guess. 4.0 UW GPA, 4.4 W GPA and good ECs some awards within and outside school. Her school doesn’t rank and she doesn’t have any hook.
What is your advise on retaking SAT, if it is available?
