I think her scores are fine. No need to retake. I asked because some students are below 700 in one score and then have an 800 in the other.
I would have her focus her energy on her essays. If this is your first going through the process be forewarned that there are a ton of essays to write. The common app essay is just one of many. Each school has their own additional essays. She may also then have honors college essays to write. My D applied to 8 schools and wrote 19 unique essays.
