Old MCAT Score Converter 2026

If you have an old MCAT score from the pre-2015 exam, the first thing to know is this:

• AAMC does not publish an official old-to-new MCAT concordance table
• but AAMC does publish official percentile tables for both the final old MCAT exam and the current MCAT exam

That means the most defensible way to convert an old MCAT total score to the current MCAT scale is by percentile matching.

That is exactly what this tool does.

What This MCAT Converter Is Actually Doing

This page compares:

• the old MCAT total score scale: 3-45
• the current MCAT total score scale: 472-528

using official AAMC percentile tables on both sides.

The process is:

1. Look up the official percentile for your old MCAT total score.
2. Find the current MCAT total score with the same percentile, or the nearest percentile if there is no exact match.
3. Show the converted current-score result, including a range if more than one score qualifies.

So this is not a fake formula and not a made-up internet conversion chart.

It is a percentile-based converter built from official AAMC tables.

Why There Is No Perfect Old-to-New MCAT Formula

The old MCAT and the current MCAT are not just the same exam on different number scales.

The exam changed in 2015, including:

• the total score scale
• the section structure
• the content blueprint

The current MCAT has four scored sections, while the older exam used a different section structure and score profile.

That is why a clean one-number formula such as:

• "old 31 always equals current 511"

would overstate the precision.

The more defensible comparison is:

• "old 31 and current 511-512 sit in roughly the same percentile neighborhood"

Official Data Used

This tool uses two official AAMC data sources:

1) Final old MCAT percentiles

AAMC publishes a final old-MCAT percentile table for exams administered from January 2012 through September 2014.

Examples from that official table:

• 30 = 79th percentile
• 25 = 49th percentile
• 33 = 91st percentile

2) Current MCAT percentiles

AAMC also publishes the current MCAT percentile table effective May 1, 2025 through April 30, 2026.

Examples from that official table:

• 510 = 79th percentile
• 500 = 49th percentile
• 515 = 91st percentile

Those examples are exactly why percentile-based conversion makes sense.

What Counts as an Accurate Result Here

There are two different meanings of "accurate."

Accurate to official source data

Yes. This tool uses official AAMC percentile tables only.

Accurate as an official AAMC concordance

No, because no such concordance exists.

The tool is accurate in the sense that it:

• uses the official old-MCAT percentile table
• uses the official current-MCAT percentile table
• matches scores by percentile as transparently as possible

It is not official in the sense of:

• an AAMC-authored old-to-new score conversion chart

Why Some Scores Convert to Ranges

The tool sometimes shows a range instead of one exact score. That is not a bug.

Ranges appear when:

• multiple current MCAT scores share the same official percentile
• multiple old MCAT scores share the same percentile
• the nearest percentile match is tied across two adjacent score points

Examples:

• an old 38 sits at 99th percentile, which corresponds to current 522-523
• an old 31 sits at 83rd percentile, which lands between current 511 (82nd) and 512 (84th)
• very high old scores can map to a broader current range because several top-end scores are all reported at 100th percentile

Why We Do Not Convert Section Scores

This page is intentionally limited to total scores.

We do not convert old MCAT section scores because:

• the section structures changed
• the exam blueprint changed
• AAMC does not publish a section-level old-to-new concordance

Trying to map old Verbal Reasoning or old Biological Sciences directly onto the current four-section MCAT would create a false sense of precision.

When To Use This Tool

Use it when:

• you have an older MCAT score from before the 2015 exam change
• you want a practical comparison on the current 472-528 scale
• you want a result based on official AAMC percentile tables rather than a third-party guess

Do not use it as:

• an official AAMC concordance
• a section-score converter
• a predictor of admissions outcomes by itself

Important Limitation

Current MCAT percentiles are updated annually by AAMC.

That means this converter can shift slightly over time even if the underlying old-MCAT percentile table stays fixed.

This version uses the current table effective May 1, 2025 to April 30, 2026, because that is the most relevant official percentile frame for current applicants.

FAQ

Is old 30 roughly the same as current 510?

Yes. In the official AAMC tables, both old 30 and current 510 sit at the 79th percentile.

Is old 33 roughly the same as current 515?

Yes. Both sit at the 91st percentile in the official AAMC tables used here.

Why do top old scores map to ranges?

Because multiple top-end current MCAT scores share the same official percentile band, especially at 99th-100th percentile.

Can I compare old and new MCAT scores directly without percentiles?

Not cleanly. Percentile is the most defensible bridge because the score scales and exam structure changed.
