LizzyM score calculator
The LizzyM score is an informal way to compare your stats with a medical school's. It was posted on the Student Doctor Network forums by an admissions committee member who goes by LizzyM. The original formula is GPA x 10 + MCAT on the old 3 to 45 scale. For today's 472 to 528 MCAT, SDN's calculator first rescales your score to that old scale.

What is the LizzyM score?
It is a rough way to see how your GPA and MCAT compare with a school's typical admitted student. A Student Doctor Network forum member who goes by LizzyM, an admissions committee member, described it: work out "(GPA*10) +old MCAT" for yourself, then compare it with the same number for the school you are aiming at. It spread on SDN, which now runs its own calculator.
How is the LizzyM score calculated?
The original formula was made for the MCAT used until 2015, scored 3 to 45:
LizzyM score = GPA x 10 + MCAT (3 to 45)
Today's MCAT is scored 472 to 528. SDN's calculator rescales it onto the old range and keeps the rest of the formula:
LizzyM score = GPA x 10 + ((MCAT - 472) / 56) x 42 + 3
So a 3.70 GPA gives 37.0, and a 512 MCAT becomes 33.0 on the old scale, for a score of 70.0. This calculator uses that formula. LizzyM herself said on SDN that she no longer remembers the arithmetic for the new MCAT, and other sites convert scores by percentile instead, so a score from another calculator can differ by a point or two.
How do you read your score?
On its own the number means little. Compare it with each school's score, worked out the same way from that school's median GPA and MCAT, which the AAMC publishes in MSAR. SDN's calculator groups schools as above, near or below your score, and calls a school a target when it is within 3 points. Treat it as a first sort of your list, not a verdict.
What are the limits of the LizzyM score?
- It is an informal forum heuristic. The AAMC does not publish it and schools do not use it. SDN itself says it is an early screen, not an admissions prediction.
- It only uses two numbers. It leaves out your science GPA, grade trend, state residency, clinical and research work, essays, letters and interviews, and a school's mission.
- It treats GPA and MCAT as interchangeable, so it works worst for uneven profiles, such as a high GPA with a low MCAT.
How does it compare with official data?
For real numbers, use the AAMC. Its FACTS tables include an MCAT and GPA grid of applicants and acceptees to US MD schools, which shows the share of applicants accepted in each GPA and MCAT range. That grid is a better guide to your overall odds, and MSAR is the place for each school's medians. Use the LizzyM score as a quick first sort of your school list, then check it against both.
Got the interview? Practice it
A school's invitation is when the interview starts to matter. Practice medical school interview questions out loud with Confetto's AI interviewer, which follows up and gives feedback on every answer.

What is a good LizzyM score?
There is no fixed good score. The idea is to compare your score with a school's own score, worked out from that school's median GPA and MCAT. SDN's calculator calls a school a target when it is within 3 points of your score.
How do you calculate the LizzyM score with the new MCAT?
SDN's calculator uses (GPA x 10) + (((MCAT - 472) / 56) x 42 + 3). The second part turns a 472 to 528 MCAT into the old 3 to 45 scale, so the original formula still works.
Do medical schools use the LizzyM score?
No. It came from a forum post, not from the AAMC or any school. Schools read your whole application, and the AAMC does not publish or use a LizzyM score.
Should I use my cumulative or science GPA?
SDN's formula uses your cumulative GPA. Schools also look at your science GPA, so check both against each school's data.
Where can I find a school's median GPA and MCAT?
The AAMC's Medical School Admission Requirements (MSAR) lists each school's median GPA and MCAT, and the AAMC FACTS tables show acceptance rates by MCAT and GPA for all applicants.
