Score smarter. Plan college with confidence.
Most score calculators are walled-garden tools from test-prep companies trying to sell you a course. CalcBold’s Education calculators use the College Board, ACT, and NCES public conversion tables directly — same percentile math, no upsell. Drop your SAT/ACT/AP/test scores or letter grades and get the verdict (composite, percentile, college tier band) plus a plain-English insight on what the number actually opens up. Free, no signup, K-12 + college-admissions focus.

Frequently Asked Questions
The most common questions we get about this calculator — each answer is kept under 60 words so you can scan.
Where do CalcBold’s Education calculators get their score conversion tables?
Directly from College Board (SAT concordance + percentile tables, AP score distributions, AP credit-granting policies), ACT.org (composite + section percentile, ACT-to-SAT concordance jointly published with College Board), and NCES (High School Transcript Study for GPA distributions). The conversion tables are reviewed every admission cycle (typically September) and the calculator pages list the specific source URL + access date in the methodology block.Why is there no College GPA calculator here?
Because the College GPA SERP is dominated by university .edu domains (Harvard, Stanford, Berkeley) that publish institution-specific GPA calculators. Competing on SERP for ‘college GPA calculator’ against .edu authority is a 2-3 year backlink-building investment that doesn’t pencil for an independent calculator hub. We focus on the score-prediction calcs where SERPs are wide-open (SAT, ACT, AP, HS GPA, test-grade %) and college admissions / test-prep companies have neglected the free-utility space.Are the percentile rankings current?
Yes — the calculators use the most recent published year of College Board + ACT.org percentile data (2026 admission cycle). Percentiles shift slightly year-to-year as test populations grow and score distributions shift. The biggest shifts happened during the digital-SAT transition (2024); current percentiles have stabilized. We re-verify the tables every September when College Board releases its annual report.Do these calculators work for international students?
The SAT + ACT + AP calcs work identically for international students — same score scales, same percentile tables. The HS GPA calculator assumes US-style 4.0 unweighted / 5.0 weighted scales; for IB diploma scoring (1-7 per subject + 3 bonus), UK A-Levels (A*-E), or German Abitur (1.0-4.0 inverted), use the Test Score (%) calculator with custom grading scale settings. International credential evaluation services (WES, ECE) handle the cross-system conversion that this calculator hub does not.
