The MCAT Score Calculator helps students convert their practice test results into an estimated official score on the 472–528 MCAT scale. This calculator is ideal for benchmarking progress, simulating test-day performance, and identifying which section—Chemical/Physical, CARS, Biological/Biochemical, or Psychological/Social—offers the highest potential score gain.
An MCAT Score Calculator transforms your practice test results into an estimated scaled score on the MCAT 472–528 range. You input correct answer counts for each of the four sections: Chemical and Physical Foundations (CP), Critical Analysis and Reasoning Skills (CARS), Biological and Biochemical Foundations (BB), and Psychological and Social Foundations (PS).
The calculator converts your raw points into normalized section percentages, estimates each section’s scaled score (118–132), and combines them into a total composite score. Since the AAMC (Association of American Medical Colleges) adjusts scores using statistical equating for each exam version, this tool provides a reliable approximation—perfect for self-assessment, not official prediction.
Each correct question earns one raw point, and there’s no penalty for wrong answers. Standard section totals are: \(n_{\mathrm{CP}}=59\), \(n_{\mathrm{CARS}}=53\), \(n_{\mathrm{BB}}=59\), and \(n_{\mathrm{PS}}=59\). When available, the calculator uses official conversion charts. Otherwise, it applies a linear or piecewise-linear interpolation model to estimate scaled scores. The total scaled score is then summed across sections (range 472–528), along with an indicative percentile estimate.
Transparent equations show every calculation step, allowing students and tutors to analyze score composition and identify high-leverage improvement areas.
Section percentages and total raw points:
\[ p_i=\frac{r_i}{n_i},\qquad R=\sum_i r_i,\quad i\in\{\mathrm{CP},\mathrm{CARS},\mathrm{BB},\mathrm{PS}\}. \]Section scaled score (model when chart absent):
\[ S_i \approx 118 + 14\,p_i \quad\text{(linear illustration)},\ \ \text{or piecewise between anchors }(r_j,S_j). \]Composite scaled score:
\[ S_{\text{total}}=\sum_i S_i,\qquad 472\le S_{\text{total}}\le 528. \]Indicative percentile (illustrative only):
\[ \widehat{\mathrm{Pct}}=\Phi\!\left(\frac{S_{\text{total}}-\mu}{\sigma}\right), \]with reference \((\mu,\sigma)\) based on practice distribution assumptions.
Raw Scores: CP \(40/59\), CARS \(37/53\), BB \(43/59\), PS \(44/59\). Estimated Section Scores: \(S_{\mathrm{CP}}\approx127\), \(S_{\mathrm{CARS}}\approx128\), \(S_{\mathrm{BB}}\approx128\), \(S_{\mathrm{PS}}\approx128\). Composite \(\approx 511\).
Raw Scores: CP \(50/59\), CARS \(45/53\), BB \(51/59\), PS \(52/59\). Estimated Section Scores \(\approx 130,130,130,130\). Composite \(\approx 520\).
Starting CARS: \(30/53\Rightarrow S_{\mathrm{CARS}}\approx126\). After +4 correct: \(34/53\Rightarrow S_{\mathrm{CARS}}\approx127\). Net composite gain \(\approx +1\) point. Combine with CP section improvement for greater gains.
No. Actual AAMC scoring varies per test form. Use this calculator for practice estimation and study planning.
Most practice forms use: CP 59, CARS 53, BB 59, and PS 59. Always verify totals with your prep materials.
No. Incorrect or blank answers do not reduce your score, so guessing is statistically beneficial.
Linear scaling provides a reasonable approximation for practice tests, though extreme scores may vary slightly from real AAMC distributions.
Yes. You can view individual section percentages, scaled scores, and combined composite output for complete performance insight.
Many medical schools consider 510+ competitive, while top-tier programs often expect 515–520+.
Yes. Percentiles are recalibrated annually based on candidate performance. This tool shows approximate percentile ranges only.
Run “what-if” scenarios to find which section gives the best score return per question. Focus on timing, critical reading, and data reasoning.
Yes. Average your section-scaled scores across several tests to measure consistency and improvement trends.
No. Field-test questions are unscored and do not impact your raw or scaled totals.
Yes. Most practice calculators round section-scaled scores to the nearest whole number before computing the composite total.
Differences arise from varying interpolation methods, conversion tables, or scaling assumptions. Align chart data for valid comparison.
