Quick Answer
A PREview retake can make sense if your first attempt was disrupted, if you made clear preparation mistakes that you can fix, or if your score is meaningfully below the range you expected after reviewing PREview Percentiles Explained and What Is a Good PREview Score?.
A retake may not make sense if the new score would arrive too late for the schools that matter most, if your first score is already reasonable for your target list, or if retesting would pull time away from higher-impact application work.
The most important rule: do not schedule a retake just because PREview can be retaken. Use the retake only if the likely benefit is stronger than the timing cost.
