Is the MCAT the Hardest Exam? A Deep Dive into Difficulty and Comparisons

MCAT Study Time Estimator

This tool helps estimate how many hours you should dedicate to prepare for the MCAT based on your target score and current baseline.

MCAT is a standardized test used by U.S. and Canadian medical schools to assess applicants' knowledge of natural, behavioral, and social sciences, as well as critical reasoning skills. Administered by the AAMC (Association of American Medical Colleges), the exam has become a rite of passage for anyone dreaming of a medical career. But does its reputation for grueling content make it the hardest exam out there?

What Makes an Exam "Hard"?

Hardness isn’t just about the number of questions. Psychometric researchers break difficulty down into four pillars:

  • Content breadth: how many distinct topics you must master.
  • Time pressure: the ratio of questions to minutes.
  • Scoring nuances: whether a single mistake can sink your score.
  • Preparation demand: typical study hours and resource intensity.

For the MCAT scoring system, each of the four sections is scored on a 118‑132 scale, yielding a total ranging from 472 to 528. A single low sub‑score can pull down the overall result, which raises the stakes compared with exams that use a simple pass/fail metric.

Inside the MCAT: Structure and Stats

The current version of the MCAT consists of four sections:

  1. Biological and Biochemical Foundations of Living Systems (59 questions)
  2. Chemical and Physical Foundations of Biological Systems (59 questions)
  3. Psychological, Social, and Biological Foundations of Behavior (59 questions)
  4. Critical Analysis and Reasoning Skills (CARS) - 53 questions

That totals 230 multiple‑choice items to be completed in 7.5 hours, including optional breaks. The official AAMC data shows an average test‑taker spends about 300‑350 hours studying, with top‑percentile students often logging 500+ hours.

Pass rates, measured by the percentage of students scoring above a 508 benchmark (roughly the 50th percentile), hover around 78% for first‑time takers. While that sounds respectable, the high variance in sub‑scores means many aspirants must retake the exam to reach a competitive 515‑520 range.

How the MCAT Stacks Up Against Other "Hard" Exams

To gauge whether the MCAT truly sits at the pinnacle of difficulty, we can compare it with three other exams notorious for their rigor: the United States Medical Licensing Examination Step 1, the Bar exam, and the Certified Public Accountant (CPA) exam.

Comparison of MCAT, USMLE Step 1, Bar Exam, and CPA Exam
Exam Typical Length Number of Questions Average Study Hours Pass Rate (first attempt) Scoring Model
MCAT 7.5hours 230 300‑350hrs 78% 538‑472 scaled score
USMLE Step1 8hours 280 400‑600hrs 94% (2022) 1‑300 scaled score
Bar Exam 2days (6hrs each) ≈ 2000 (multiple‑choice + essays) 350‑450hrs 71% (nationwide avg) Pass/Fail
CPA Exam 4 sections × 4hrs ≈ 600 300‑400hrs 53% (first‑time) Pass/Fail

What emerges?

  • The MCAT’s MCAT difficulty is comparable to the Bar exam in terms of study time, but the Bar has a lower pass rate, suggesting a steeper hurdle for many candidates.
  • USMLE Step 1 requires the most hours and has a more generous pass rate because many students sit for it after completing two years of medical school.
  • The CPA exam has the lowest first‑time pass rate, despite a slightly shorter total testing time than the MCAT.

Thus, the MCAT is certainly up there, but whether it’s the absolute hardest depends on the metric you prioritize.

Why Perception Often Overstates the MCAT's Hardness

Why Perception Often Overstates the MCAT's Hardness

Surveys of pre‑medical students repeatedly rank the MCAT as their most stressful academic hurdle. The main drivers are:

  • High‑stakes impact on medical school admissions.
  • Broad interdisciplinary content that forces students to master chemistry, physics, biology, psychology, sociology, and literary analysis all at once.
  • Limited testing windows (once per year for most of the year), creating a sense of scarcity.

However, data from the AAMC shows that students who follow a structured 12‑week prep plan with full‑length practice exams tend to score within 5 points of their target, regardless of prior GPA. In contrast, the Bar exam’s variability is higher across states because each jurisdiction selects its own test format and passing score.

Preparation Powerhouses: Turning Difficulty into Manageable Steps

Professional test‑prep firms have built entire ecosystems around the MCAT. Among them, Kaplan offers a flagship 12‑week course that includes 12 full‑length practice exams, weekly live classes, and a personalized study schedule. Independent reviews cite a median score bump of 6‑9 points for students who complete the program.

Other notable resources include the Princeton Review, the NBME's official practice exams, and free question banks on the AAMC website. The key is to mix content review with timed practice, especially for CARS, which many test‑takers find the most unpredictable.

Practical Strategies to Tackle the MCAT

  1. Diagnose your baseline. Take an un-timed NBME practice test early to see where you stand across the four sections.
  2. Build a study calendar. Allocate at least 2hours daily for content review, 1hour for practice questions, and a full‑length exam every two weeks.
  3. Prioritize weak spots. Use the diagnostic results to focus on low‑scoring domains-often physics for biology majors and CARS for humanities majors.
  4. Simulate test day. Replicate the 7.5‑hour schedule, including breaks, at least three times before the real exam.
  5. Review thoroughly. After each practice test, spend twice as much time analyzing every wrong answer as you did taking the test.

Students who embed these habits report lower anxiety and steadier score improvements, turning the perceived "hardest" label into a manageable challenge.

Where to Go Next?

If you're convinced the MCAT is your biggest obstacle, the next logical step is to draft a 12‑week study plan tailored to your baseline scores.

Frequently Asked Questions

Frequently Asked Questions

Is the MCAT harder than the USMLE Step 1?

Hardness depends on perspective. The MCAT covers a broader range of undergraduate subjects, while USMLE Step 1 focuses on first‑year medical school material. In terms of total study hours, Step 1 often demands more, but the MCAT’s scoring model penalizes uneven performance more sharply.

What is a realistic study timeline for the MCAT?

Most successful candidates follow a 12‑ to 16‑week plan, dedicating 15‑20hours per week. Total preparation time usually falls between 300 and 350hours, with an extra 50‑hour boost for those aiming for scores above 515.

Can I retake the MCAT if I’m unhappy with my score?

Yes. The AAMC allows up to three attempts per year, and most schools consider the highest score. However, many programs also look at the number of attempts, so it’s best to aim for your target the first time.

How does CARS differ from the other MCAT sections?

CARS tests reading comprehension and analytical reasoning without any science content. It requires speed, flexibility, and an ability to infer arguments from dense passages-skills that often trip up science‑focused students.

Are commercial prep courses worth the cost?

For most students, a structured course (e.g., Kaplan or Princeton Review) adds discipline, high‑quality practice exams, and expert feedback. Studies from the AAMC show a median score increase of 5‑7 points for course participants versus self‑study alone.
