The Hardest Part of the MCAT: Unveiling the Mystery!

Ari Horesh

The Medical College Admission Test (MCAT) has earned its reputation as a notoriously challenging exam for pre-med students. It's a high-stakes test that can determine the direction of your future medical career. But with so many different topics and sections to tackle, what is the hardest part of the MCAT? Let's dive deep into this enigmatic question and reveal the truth about the most difficult MCAT section!

Meet the Four Formidable MCAT Sections

Before we unveil the hardest part of the MCAT, let's quickly recap the four main sections of the exam:

Chemical and Physical Foundations of Biological Systems (Chem/Phys): This section tests your knowledge of general chemistry, organic chemistry, biochemistry, physics, and biology. It assesses your ability to reason about scientific concepts and principles.

Critical Analysis and Reasoning Skills (CARS): The CARS section measures your ability to comprehend complex texts, analyze arguments, and draw logical conclusions. It's unique as it doesn't require any specific scientific background and focuses solely on your critical thinking and reading comprehension skills.

Biological and Biochemical Foundations of Living Systems (Bio/Biochem): Here, your understanding of biology, biochemistry, organic chemistry, and general chemistry will be put to the test. This section emphasizes the processes unique to living organisms, such as growth, reproduction, and homeostasis.

Psychological, Social, and Biological Foundations of Behavior (Psych/Soc): This section evaluates your ability to understand the behavioral and sociocultural aspects of human health. It covers topics such as psychology, sociology, and biology.

Now that we're familiar with the MCAT sections let's discuss which one is considered the hardest by most pre-med students.

The CARS Section: The Ultimate MCAT Challenge?

Many students believe the CARS section is the hardest part of the MCAT. Why? Here are a few reasons why this section has gained its notorious reputation:

Time Pressure

CARS is a timed section, with 90 minutes allotted to answer 53 questions based on nine passages. The time pressure can be overwhelming, as it requires you to read quickly while maintaining a high level of comprehension and analytical thinking.

No Background Knowledge Required

Unlike other MCAT sections that rely on scientific knowledge, CARS focuses solely on your critical reading and reasoning skills. This means that you can't rely on your background knowledge to help answer the questions. Some students find this aspect challenging, as they cannot use their strengths in specific subjects to their advantage.

Complex Texts and Dense Language

The CARS section presents passages with intricate arguments and dense language, often involving topics that may be unfamiliar or unrelated to the medical field. This complexity requires students to adapt their reading strategies and think critically about the content.

Limited Practice Material

It can be challenging to find adequate practice material specifically designed for the CARS section. While there are plenty of resources available for the other sections, the unique nature of CARS makes it more difficult to create relevant practice materials.

Honorable Mentions: The Other Tough MCAT Sections

While the majority of pre-med students may find the CARS section the most difficult, others have their own personal struggles with the remaining sections. Here's a brief overview of why some students might consider these sections challenging:


This section demands a solid understanding of multiple scientific disciplines, which can be daunting for some students. Moreover, the integration of multiple subjects in single questions can be particularly tricky, requiring a strong foundation in all the covered areas.


With a strong emphasis on biological processes and systems, the Bio/Biochem section can be challenging for those who struggle with the intricate details of living organisms. Additionally, the section demands a deep understanding of biochemistry, which can be a complex and challenging subject in itself.


This section may prove difficult for students who haven't had much exposure to psychology and sociology. The breadth of topics covered, from social inequality to cognitive processes, requires a well-rounded understanding of the behavioral and social aspects of human health.

Conquering the Hardest Part of the MCAT: Top Tips

No matter which section you find the most difficult, here are some essential tips to help you conquer the hardest part of the MCAT:

Identify Your Weaknesses: Determine which section you struggle with the most and focus on improving your performance in that particular area.

Create a Study Plan: Develop a study plan that caters to your specific needs and includes a balanced approach to mastering all the MCAT sections.

Practice, Practice, Practice: Utilize practice materials and take full-length practice exams to familiarize yourself with the test format and build your test-taking stamina.

Build a Strong Foundation: Ensure that you have a solid understanding of the core concepts and principles for each section. This foundation will help you tackle more complex questions with confidence.

Develop Time Management Skills: Learn to pace yourself and allocate appropriate time for each question. This is especially crucial for the CARS section, where time management plays a vital role in your success.

Seek Help: Don't be afraid to ask for assistance from teachers, tutors, or peers. They can provide valuable insights and guidance on how to overcome your weaknesses.

Stay Positive and Persistent: Embrace a positive mindset and remain persistent in your efforts. Overcoming the hardest part of the MCAT takes time, dedication, and resilience.

In Conclusion: The Hardest Part of the MCAT is Subjective

While many students consider the CARS section to be the most challenging, the hardest part of the MCAT ultimately depends on your individual strengths and weaknesses. The key to success is understanding your unique challenges, focusing on improvement, and utilizing effective strategies to conquer the exam.

So, roll up your sleeves, face your fears, and tackle the hardest part of the MCAT head-on! Remember, every great doctor has faced this hurdle, and with determination, persistence, and a strategic approach, you too can triumph over this formidable exam!

As you embark on your journey to conquer the hardest part of the MCAT, remember that you are not alone. Thousands of aspiring doctors have faced the same challenges and emerged victorious. Armed with the right knowledge, effective strategies, and a positive mindset, you have the power to overcome any obstacle and achieve your dreams of entering medical school.

So, keep pushing forward, and soon, you'll be looking back at the MCAT as just another stepping stone on your path to becoming a successful physician. The journey may be challenging, but the rewards are well worth the effort. Good luck, future doctors!
