These principles are fundamental to various aspects of medicine, including drug interactions, cellular processes, and the functioning of the human body. Medical schools want to ensure that their students have a solid foundation in these areas, which is why the MCAT assesses these skills.

Critical Analysis and Reasoning Skills (CARS)

This section of the MCAT is distinct from the other three science-oriented sections. It assesses your ability to read and understand complex texts, critically analyze information, and draw well-reasoned conclusions. This section primarily focuses on your verbal reasoning, reading comprehension, and critical thinking skills. Here's a more detailed overview of the CARS section:

1. Reading Comprehension:

• The CARS section presents you with passages from a variety of disciplines, including the humanities, social sciences, and natural sciences.
• These passages are typically non-scientific in nature, which means you don't need prior knowledge of specific scientific concepts to answer the questions. Instead, you're expected to extract meaning from the texts.

2. Critical Thinking:

• As you read the passages, you should analyze and evaluate the arguments, opinions, and information presented.
• You'll encounter questions that require you to identify the author's main argument, the evidence used to support it, and the author's tone and perspective.
• Critical thinking is crucial as you must assess the logical structure of the passages, including identifying premises and conclusions.

3. Inference and Interpretation:

• CARS questions often ask you to make inferences, draw conclusions, and identify implications based on the information presented in the passages.
• You'll be challenged to extrapolate beyond the given text and connect ideas across the passage.

4. Evaluation of Perspective:

• Understanding the perspective of the author is vital. This includes recognizing the author's biases, motivations, and potential gaps in their reasoning.
• You may be asked to assess the strengths and weaknesses of the author's argument.

5. Passage-Based Questions:

• The majority of CARS questions are based on the passages. This means your ability to absorb and retain information from the text is key to your success in this section.
• The questions might require you to refer back to specific lines or paragraphs within the passage to support your answers.

Why is the CARS section important?

The CARS section is crucial because it assesses skills that are highly relevant in the field of medicine. Medical professionals often need to analyze complex medical literature, communicate effectively with patients, and critically evaluate research findings. The ability to understand and interpret written material is vital in medical school and throughout a medical career.

Biological and Biochemical Foundations of Living Systems

This section on the MCAT is a critical part of the exam that evaluates your knowledge of biology, biochemistry, and organic chemistry. This section is designed to assess your understanding of the fundamental principles governing living organisms and their biochemical processes. Here's a more detailed overview of what this section covers:

1. Biology:

• This section may include questions on various aspects of biology, such as cellular biology, genetics, and human systems.
• Cellular biology covers topics related to cell structure, functions, and processes, including cell division and cellular transport.
• Genetic questions encompass principles of inheritance, DNA structure, gene expression, and genetic variation.
• Questions related to human systems focus on human anatomy and physiology, including the functioning of organ systems like the cardiovascular, respiratory, and nervous systems.

2. Biochemistry:

• Biochemistry is a significant part of this section, emphasizing the molecular and chemical processes within living organisms.
• You may encounter questions about protein structure and function, enzyme kinetics, and metabolic pathways.
• Understanding concepts such as DNA replication, transcription, translation, and the regulation of gene expression is crucial.

3. Organic Chemistry:

• Organic chemistry topics are interwoven with biochemistry in this section.
• Organic chemistry questions may focus on the organic molecules and reactions that play a vital role in biological systems.
• This could include concepts like functional groups in biomolecules, biochemical reactions, and the chemistry of biological compounds.

Why is this section important?

The Biological and Biochemical Foundations of Living Systems section is central to the MCAT because it directly relates to medicine. Understanding the biological and biochemical processes of the human body is essential for medical professionals.

Psychological, Social, and Biological Foundations of Behavior
