PSAT Scoring Guide
How scores are calculated, what they mean, and how to reach your goal score.
Scoring Overview
PSAT scoring mirrors the digital SAT: two section scores (R&W and Math) each 160–760, totaling 320–1520. The test is section-adaptive: your performance on the first R&W or Math module determines the difficulty of the second. The PSAT Selection Index (used for National Merit) is 2 × (R&W + Math_subscore_1-38)/10. The 99th percentile cutoff varies by state but typically falls around a Selection Index of 210+.
Score Scale

Study Tips
- 1.Practice on the official Bluebook app so you're comfortable with the digital interface.
- 2.Learn Desmos inside out — it's faster than a handheld calculator once you know it.
- 3.Review algebra fundamentals first — they're ~35% of Math.
- 4.Read a variety of non-fiction to boost R&W speed.
- 5.Take 1–2 full-length practice tests in the 6 weeks before the PSAT.
