Hi my MCAT and GPA fall in the average of lower-upper tier and upper-mid-tier schools like Stanford, Columbia, NYU, Dartmouth, Mayo Clinic, but I have a 9 in the BS section of the MCAT (BS on my session I found particularly difficult, and PS and VR particularly easy). Assuming that I have somewhat of a chance to be admitted to those schools, would these schools screen me out simply because of my BS of 9?
