<p>I say go for it if you feel like you didn’t perform your best this time around. If you are really satisfied with a 2340, then I wouldn’t retake. Taking it a second time only in hopes that you might get lucky and improve is pretty useless, only retake that score if you are disappointed with it. And yes, as JasoninNY has pointed on, studies have shown that acceptance rates are exponentially higher at 2350+ contrary to popular belief. 2400 scorers have over 50% acceptance rates at HYP which is quite impressive. As a personal anecdote, I just retook my 2370 in January today, so its really up to you.</p>
