Mcat Essay Score

The Medical College Admission Test (MCAT) assesses mastery of basic scientific concepts, problem solving, and critical thinking, as well as general writing skills.

The Medical College Admission Test (MCAT) assesses mastery of basic scientific concepts, problem solving, and critical thinking, as well as general writing skills. The skills tested are those identified by medical professionals as essential for success in medical school and as a doctor.

The MCAT test is broken into four sections: Physical Sciences, Biological Sciences, Verbal Reasoning, and the Writing Sample. The information below will help you determine what to focus your study on when completing MCAT preparation.

MCAT prep for the sciences

The Physical Sciences section measures your mastery of basic physics and general chemistry concepts. There are 7 to 9 passages; each passage is approximately 250 words in length, and describes a situation or problem. Most of the questions are tied to one of these passages, but some are independent of any passage. All questions are multiple choice.

The Biological Sciences section assesses your understanding of concepts from biology and organic chemistry. There are 7 to 9 passages; each passage is approximately 250 words in length, and describes a situation or problem. On the average MCAT, most of the questions are tied to one of these passages, but some are independent of any passage. All questions are multiple choice.

MCAT prep for reading and writing

The Verbal Reasoning section gauges your ability to understand, analyze, apply, and evaluate information from a prose passage. All questions are multiple choice; each of the questions is attached to one of five to six passages. Each passage is approximately 500 words long, and covers topics from the humanities, social sciences, and natural sciences that are not covered in other sections of the MCAT. No prior knowledge is required to answer these questions; only your ability to read and understand the passage is tested.

The Writing Sample section consists of two essays. Each essay is written in response to a prompt. A prompt consists of a topic sentence and instructions for three writing tasks you are to complete within the essay. The first task will always ask you to explain the given statement; the other two tasks will vary with each prompt. Your essays will be judged on how well they develop a central idea, how well they combine multiple, complex ideas together, how clearly written they are, and how well they adhere to standard rules of grammar, punctuation, and usage.

The computerized MCAT test experience

  • The MCAT exam is now administered entirely on a computer. No more paper and pencil versions of the exam will be given.
  • Scratch paper and pencils will be provided if you need them, but you will not be allowed to remove them from the testing room.
  • You will be able to review and make changes to answers within a section until you reach the time limit for that section. However, once you have completed a section, you cannot view or change any answers in it.
  • You will type your responses in the Writing Sample section. You will be able to edit your response, and cut, copy, and paste sections if necessary. However, no spell-checker will be available.
  • A timer will be visible on the screen throughout the test. The time will count down in each section. If you finish a section early, you can move on to the next section.

MCAT test scoring

You will receive scaled scores for each section. For the Physical Sciences, Verbal Reasoning, and Biological Sciences sections, scaled scores range from 1 to 15.

Each essay in the Writing Sample section is scored by two different readers, each of which assigns it a score from 1 to 6. The total raw score is then converted to a scaled score, which is a letter from J to T. A score of "T" on the Writing Sample section is the highest possible score.

You will be able to get your score report approximately 30 days after you complete the MCAT exam.

Scores / grades used byMedical colleges (mostly in United States and Canada).

The Medical College Admission Test (MCAT) is a computer-basedstandardized examination for prospective medical students in the United States, Australia,[9] Canada, and Caribbean Islands. It is designed to assess problem solving, critical thinking, written analysis and knowledge of scientific concepts and principles. Prior to 2006, the exam was a paper-and-pencil test; since 2007, all administrations of the exam have been computer-based.

The most recent version of the exam was introduced in April 2015 and takes 7.5 hours to complete. The test is scored in a range from 472 to 528.


Moss Test: 1928–46[edit]

In the 1920s, dropout rates in US medical schools soared from 5% to 50%,[10] leading to the development of a test that would measure readiness for medical school. Physician F. A. Moss and his colleagues developed the "Scholastic Aptitude Test for Medical Students" consisting of true-false and multiple choice questions divided into six to eight subtests. Topics tested included visual memory, memory for content, scientific vocabulary, scientific definitions, understanding of printed material, premedical information, and logical reasoning. The score scale varied from different test forms. Though it had been criticized at the time for testing only memorization ability and thus only readiness for the first two years of medical school, later scholars[who?] denied this. In addition to stricter medical school admission procedures and higher educational standards, the national dropout rate among freshman medical students decreased from 20% in 1925–1930 to 7% in 1946.

A simpler test: 1946–62[edit]

Advancements in test measurement technology, including machine scoring of tests, and changed views regarding test scores and medical school readiness reflected the evolution of the test in this period. The test underwent three major changes. It now had only four sub tests, including verbal ability, quantitative ability, science achievement, and understanding modern society. Questions were all in multiple-choice format. Each subtest was given a single score, and the total score was derived from the sum of the scores from the subtests. The total score ranged from 200–800. The individual scores helped medical school admission committees to differentiate the individual abilities among their candidates. Admission committees, however, did not consider the "understanding modern society" section to be of great importance, even though it was created to reward those with broad liberal arts skills, which included knowledge of history, government, economics, and sociology. Committees placed greater emphasis on scores on the scientific achievement section as it was a better predictor of performance in medical school.

From 1946 to 1948, the test was called the "Professional School Aptitude Test" before finally changing its name to the "Medical College Admission Test" when the developer of the test, the Graduate Record Office (under contract with the AAMC) merged with the newly formed Educational Testing Service (ETS). In 1960, the AAMC transferred its contract over to The Psychological Corporation, which was then in charge of maintaining and developing the test.

Status quo: 1962–77[edit]

From 1962 to 1977, the MCAT retained much of its previous format, though the "understanding modern society" section was renamed as "general information" due to its expanded content. Handbooks at the time criticized the test as only a measure of intellectual achievement and not of personal characteristics expected of physicians. Admission committees responded to this criticism by measuring personal characteristics among their applicants with various approaches.

Phase four: 1977–91[edit]

During phase four, the MCAT underwent several changes. The "general information" section was eliminated and a broader range of knowledge was tested. At this point, topics tested included scientific knowledge, science problems, reading skills analysis, and quantitative skills analysis. Individual scores were reported for biology, chemistry, and physics rather than a composite science score, thus six different scores for the whole test were reported. The score scale changed to 1–15 as opposed to 200–800 from previous versions of the test. Cultural and social bias was minimized. Though the AAMC claimed the new version intended to evaluate "information gathering and analysis, discerning and formulating relationships, and other problem-solving skills," no research supported this claim.

New changes: 1992–2014[edit]

In 1992, the test changed again. Though the test was still divided into four subtests, they were renamed as the verbal reasoning, biological sciences, physical sciences, and writing sample sections. Questions retained the multiple-choice format, though the majority of the questions were divided into passage sets. Passage-based questions were implemented to evaluate "text comprehension, data analysis, ability to evaluate an argument, or apply knowledge from the passage to other contexts." A new scoring scale was also implemented. The total composite score, which ranges from 3–45, is based on the individual scores of the verbal reasoning, biological sciences, and physical sciences, which each have a score range of 1–15. The writing sample, which consists of two essays to be written within 30 minutes for each, is graded on a letter scale from J-T with T being the highest attainable score.

On July 18, 2005, the AAMC announced that it would offer the paper-and-pencil version of the MCAT only through August 2006. A subset of testing sites offered a computer-based version of the full-length exam throughout 2005 and 2006. A shorter, computer-based version of the test debuted in January 2007. The exam was at that point offered numerous times annually, and scored more quickly.[11][12]

MR5 and the 2015 test[edit]

The MR5 advisory committee was appointed by AAMC in fall 2008.[13] Highlights of the MR5 process were surveys of what undergraduate institutions teach and surveys of medical school faculty in which they ranked undergraduate subjects for importance in medical school curricula of the future. Late in 2011, the MR5 recommendations were formalized as core competencies that will be tested in 2015.[14] MR5 recommendations were enacted by the AAMC in 2012. The largest changes consist of testing in biochemistry, multicultural/behavioral concepts, and critical analysis/reasoning from the humanities. Because college freshmen entering in fall 2012 took a new MCAT, undergraduate premedical advisers studied the MR5 documents to translate tested core competencies into premedical course recommendations at their campuses. The MR5 MCAT revision has the potential to lead to changes in mathematics, physics, psychology, sociology, and general education recommendations in addition to changes in biology, chemistry and biochemistry. One scientific society to comment on the new MCAT and its implications for the undergraduate curriculum is the American Society for Biochemistry and Molecular Biology. Though ASBMB noted that the premedical curriculum in mathematics, physics, social sciences and the humanities is likely to change, the society confined its recommendations to coursework in biology, chemistry and biochemistry.[15]


The exam is offered 25 or more times per year at Prometric centers.[16] The number of administrations may vary each year. Most people who take the MCAT are undergraduates in their junior or senior year of college before they apply to medical school. Ever since the exam's duration was lengthened to 7.5 hours, the test is only offered in the morning.

The test, updated in 2015, consists of four sections, listed in the order that they are administered:

  • Chemical and Physical Foundations of Biological Systems
  • Critical Analysis and Reasoning Skills (CARS)
  • Biological and Biochemical Foundations of Living Systems
  • Psychological, Social and Biological Foundations of Behavior

The four sections are in multiple-choice format. The passages and questions are predetermined, and thus do not change in difficulty depending on the performance of the test taker (unlike, for example, the general Graduate Record Examination).

The first section assesses problem-solving ability in general chemistry, organic chemistry, and physics while the third section evaluates these abilities in the areas of biology and biochemistry. The Critical Analysis and Reasoning Skills section evaluates the ability to understand, evaluate, and apply information and arguments presented in prose style.

Test contents[edit]

Chemical and Physical Foundations of Biological Systems5995
Biological and Biochemical Foundations of Living Systems5995
Critical Analysis and Reasoning Skills5390
Psychological, Social and Biological Foundations of Behavior5995

The test consists of four sections, each with a maximum score of 132 points (and a minimum score of 118 points). The total MCAT score is the sum of the four section scores, and ranges from 472 to 528, with 500 being the median score.[17]

2016 scoring percentiles[edit]

The following are the scores along with their percentiles from test takers from April through September 2015. MCAT percentiles are updated every year on May1st. The average scaled score was 499.6 with a standard deviation of 10.4.[18]

Like some other professional exams (e.g. the Graduate Management Admission Test (GMAT) or the Law School Admissions Test (LSAT), the MCAT may be voided on the day of the exam if the exam taker is not satisfied with his or her performance. It can be voided at any time during the exam, or during a five-minute window that begins immediately after the end of the last section. The decision to void can only be based on the test taker's self-assessment, as no scoring information is available at the time—it takes 30–35 days for scores to be returned.

The AAMC prohibits the use of calculators, timers, or other electronic devices during the exam.[19] Cellular phones are also strictly prohibited from testing rooms and individuals found to possess them are noted by name in a security report submitted to the AAMC. The only item that may be brought into the testing room is the candidate's photo ID. If a jacket or sweater is worn, it may not be removed in the testing room.[20]

It is no longer a rule that students must receive permission from the AAMC if they wish to take the MCAT more than three times in total. The limit with the computerized MCAT is three times per year, with a lifetime limit of seven times.[21] An examinee can register for only one test date at a time, and must wait two days after testing before registering for a new test date.

Scaled MCAT exam results are made available to examinees approximately thirty days after the test via the AAMC's MCAT Testing History (THx) Web application. Examinees do not receive a copy of their scores in the mail. Nor are examinees given their raw scores. MCAT THx is also used to transmit scores to medical schools, application services and other organizations (at no cost).


Like most standardized tests, there are a variety of preparatory materials and courses available. The AAMC itself also offers a select few tests on their website.

Some students taking the MCAT use a test preparation company. Students who do not use these courses often rely on material from university text books, MCAT preparation books, sample tests, free web resources, and educational mobile applications (free/paid).


A recent study (2016), shows little to no correlation between MCAT scores and USMLE step 1 scores, as well as little to no correlation between MCAT scores and the NBME scores.[22] The MCAT also correlated poorly with the Canadian Board exam in 2016, the (MCCQE-1). [23]

The Biological Sciences section had been the most directly correlated section to success on the USMLE Step 1 exam in an article published in 2002, with a moderate correlation coefficient of .553 vs .491 for Physical Sciences and a weak correlation of .397 for Verbal Reasoning, however, these are not very well correlated with USMLE Step 1 score, as a strong correlation would be anything above 0.7, meaning that even in 2002, MCAT did not have a strong correlation with USMLE Step 1 success.[24] MCAT composite scores had previously (in article published in 2002) claimed to have some form of correlation with USMLE Step 1 success, although exact numbers are not given.[25]
