1530 ss do i retake??

800 math from june, 730 rw from nov

context: applying to the t20s, northwestern prolly ed, unc, brown, uiuc, udub, wustl, cwru, emory, uva, couple more safeties

applying for neuroscience/bio, my ec's i think are pretty good, grades are mostly strong, taking ib classes

im a rising senior and i'm focusing on essay brainstorming and stuff over the summer, idk whether a retake for a better rw score is needed

should i consider applying to more top schools or is this mix for my score good?
