Google says there is no minimum SAT requirements in Harvard but they really looking at score above average

. So it's not unthinkable that her score is even below average.
Actually, it IS unthinkable. The average SAT score is 1500 (target average, at least). Here's a link to the this coming year's graduating class's SAT scores:

The lowest were students in the 1600 (out of 2400) range, above average although not really impressive. Notice they had perfect grades, though. Harvard doesn't just look at grades/SAT, anyway. Looking at this graph, you would have thought I had a good chance of getting in to Harvard (2150 SAT, 3.8 GPA), but I basically had zero chance. They are mostly looking for kids that have excellent grades, excellent scores, AND have real accomplishments already. Examples are things like having started a business, having built something of consequence, being chess champion, being the best cellist in the country, etc etc. I bet you most of those kids in the bottom left have weighty accomplishments. Basically, there is 0% chance Malia's SAT were below average, and given her high school, they were almost certainly very high.
