516/3.95, South Asian ORM, NJ, large public undergrad, applied to 30 schools, have received 0 IIs and 4 Rs (Case, UChicago, Stanford, Rochester).

Sent all secondaries within two weeks of receiving them, mostly during July.

My app is research-heavy; because of this, my school list is relatively top-heavy. Should I retake my MCAT for a 520+ to be considered fairly? Otherwise, doesn't feel like much of a fighting chance, even with strong writing.

Also, is it time to consider reapplication, given these factors and the timeline?
