I'm interested in applying for a PhD in political science in schools like MIT, Harvard, Stanford, etc. GREs are 162V, 170Q - am still waiting for AW score but likely 3.5/4.0/4.5 (wasn't great due to 1 incomplete essay). Rest of application is reasonably strong and I should be able to sufficiently reflect my writing ability (research experience, undergraduate thesis, etc). Would appreciate some opinions about retaking GREs!
