Her odds of an admission are in the low single digits, just based on numbers alone.
Stanford receives ~8000 applications annually for 140 seats.
For the the 2018-19 application cycle, the median GPA for Stanford matriculants was 3.89 and the median MCAT was 518.
Define top school? For the top USNews schools–like NYU, WashU, JHU, etc, her MCAT scores is on the low side. Median Mcat for WashU is 522, NYU-522, JHU–519, Harvard–518 Yale–518, UCSD–517, UMichigan-517. UCLA used to require a 514 just to apply.
To put her score in perspective, a 514 is the median MCAT score for matriculants at Florida, South Florida, Sonybrook, SUNY Downstate and Western Michigan. (I know, I had to double check WMi --but it’s true…)
Every applicant should apply to a range of schools for the best odds of gaining an acceptance.
I strong suggest your D buy access to MSAR (Medical School Admission Requirements)-- available through AMCAS. $30 for 1 one year subscription. It has the GPAs and MCAT scores for every US & Canadian medical school broken down by quartiles.
