Is a 520 MCAT Worth a Retake?
A 520 is already an asset, which sets a high bar for retaking: the case has to be credible, low-risk, and aimed at a meaningfully different outcome. Retake only if three things are true: your recent full-lengths under strict conditions are clustering 523+ with stable section balance, your first test had a documented one-off disruption you can explain cleanly if asked, and your target list is unusually score-sensitive (for example, a very top-heavy set where you need every marginal edge and the rest of your file is already operating at that tier). If you can’t meet those conditions, don’t retake; the most likely outcomes are a flat score, a small drop, or a tiny gain that admissions committees discount because it doesn’t change the underlying read of your readiness.
Treat this like portfolio risk, not ego optimization: a 520 is already an asset, and the downside of damaging that asset is real. The more useful question is, “What is the highest-return use of the next 150-250 hours for my specific application?” Run a simple expected-value check: assign probabilities to scoring lower, the same, +1-2, and +3+, then ask what each outcome actually changes given your GPA trend, clinical exposure, research, service, and letters. In most cases, the higher-leverage move is to redeploy that time into sustained clinical work, deeper service continuity, or a sharper school list strategy, because those components can move an admissions decision where a 521 often won’t. A retake is justified only when it has a clear path to changing the decision context, not just the number.
