Step 1 Subjects

The question bank is organized into major foundational science disciplines so you can quickly focus on areas that require additional practice.

Question Selection by Subject

• Anatomy — 308
• Behavioral Science — 252
• Biochemistry — 158
• Biostatistics — 120
• Embryology — 76
• Genetics — 107
• Histology — 29
• Immunology — 132
• Microbiology — 347
• Pathology — 819
• Pathophysiology — 486
• Pharmacology — 551
• Physiology — 269

These counts refer to the organization of this September 2026 Hub edition.

Subject + System Segregation

One of the strongest features of the interactive format is the ability to combine a foundational discipline with a specific organ system.

You are not restricted to starting at Question 1 and progressing sequentially.

Instead, you can create targeted combinations such as:

Pathology + Cardiovascular System

Useful when reviewing cardiovascular disease mechanisms while strengthening pathology knowledge.

Pharmacology + Nervous System

Useful for practicing neurologic and psychiatric pharmacology in a system-based context.

Microbiology + Respiratory System

Useful when reviewing respiratory infections and their microbiological foundations.

Physiology + Renal System

Useful for integrating kidney physiology with clinically relevant disease mechanisms.

Biochemistry + Endocrine System

Useful for combining biochemical pathways with endocrine physiology and disease.

This structure closely reflects the integrated nature of modern Step 1 preparation.

USMLE officially states that Step 1 content is organized using an integrated framework combining organ systems and foundational science concepts, and that most questions require application rather than simple factual recall.

Create Your Own QBank Tests

The Hub interface lets you build practice sessions according to your individual study plan.

Choose Your Content

Select one or more:

• Subjects
• Systems
• Topic groups

This lets you create focused or broader practice sessions depending on your stage of preparation.

Create Multiple Tests

You are not limited to one fixed question sequence.

Create separate sessions for different disciplines or systems and return later for additional practice.

Answer Questions Interactively

Select answers directly through the online QBank interface.

This gives you an active testing workflow instead of passive PDF reading.

Review Your Answers

After practice, review each question and its associated explanation to understand the reasoning behind the correct answer.

Repeat Difficult Material

Previously studied questions can be revisited for additional review and reinforcement.

Previous Tests & Progress Tracking

Your study activity remains organized inside your Hub account.

You can:

• Open previous tests
• Review previous scores
• Identify previously attempted questions
• Revisit explanations
• Repeat difficult questions
• Identify subjects requiring more review
• Monitor progress across multiple study sessions

This is particularly useful during a long Step 1 preparation period because your work does not disappear after completing each practice session.

Questions, Explanations & Images Together

Many Step 1 questions require interpretation of clinical or scientific visual material.

Where the source question contains an associated image, it is displayed alongside the question and explanation inside the interactive environment.

This helps keep related study material together rather than requiring you to switch among separate files.

The official USMLE content description specifically notes that Step 1 may require interpretation of graphic material, tables, gross specimens, and microscopic pathology, in addition to applying basic science principles.

Major Step 1 Disciplines

USMLE currently identifies major foundational disciplines relevant to Step 1, including:

• Pathology
• Physiology
• Nutrition
• Gross Anatomy
• Embryology
• Microbiology
• Pharmacology
• Behavioral Sciences
• Biochemistry
• Histology and Cell Biology
• Immunology
• Genetics

These disciplines are integrated across clinical organ systems rather than tested only as isolated subjects.

Major Organ Systems

Interactive system-based practice can be used to focus on areas such as:

• Cardiovascular System
• Respiratory System
• Renal and Urinary System
• Gastrointestinal System
• Endocrine System
• Reproductive System
• Nervous System
• Behavioral Health
• Blood and Lymphoreticular System
• Immune System
• Musculoskeletal System
• Skin and Subcutaneous Tissue
• Multisystem Processes
• Human Development

The current official Step 1 blueprint organizes examination content across major systems including cardiovascular, gastrointestinal, respiratory/renal, reproductive/endocrine, nervous/behavioral health, musculoskeletal, immune and multisystem areas.

Designed for Modern Step 1 Preparation

Step 1 is not designed primarily as a memorization exam.

USMLE describes the examination as assessing whether students can understand and apply important foundational science concepts to medicine, particularly mechanisms underlying health, disease and therapy.

The current blueprint gives substantial emphasis to:

• Applying foundational science concepts
• Diagnosis
• Interpretation of scientific and clinical information
• Integrated system-based reasoning

This makes interactive question practice particularly useful for connecting foundational science with clinical-style problem solving.

Pathology Practice

With 819 questions categorized under Pathology, this section forms one of the largest subject groups in this September 2026 edition.

Students can combine pathology with systems such as:

• Cardiovascular
• Respiratory
• Gastrointestinal
• Renal
• Endocrine
• Neurologic
• Reproductive
• Musculoskeletal

The official USMLE Step 1 blueprint also gives pathology one of the largest discipline weightings, currently listed at approximately 45–55%, although individual questions can belong to multiple disciplines.

Pharmacology Practice

The Hub edition contains 551 questions categorized under Pharmacology.

Use these questions to reinforce concepts involving:

• Mechanisms of action
• Adverse effects
• Drug interactions
• Clinical indications
• Pharmacodynamics
• Pharmacokinetics
• Therapeutic mechanisms

Pharmacology can also be combined with individual organ systems for more focused revision.

Pathophysiology Practice

The 486-question Pathophysiology category is especially useful for connecting normal physiology with mechanisms of disease.

This supports the type of integrated reasoning emphasized by Step 1.

Microbiology Practice

The Microbiology category contains 347 questions and can be used independently or combined with organ-system categories.

Practice can focus on clinically relevant concepts related to:

• Bacteria
• Viruses
• Fungi
• Parasites
• Host-pathogen interactions
• Diagnostic principles
• Antimicrobial mechanisms

Anatomy and Embryology

The QBank includes:

• Anatomy — 308 questions
• Embryology — 76 questions

These areas can be integrated with system-focused practice to reinforce structural and developmental concepts in a clinical context.

Physiology Practice

The Physiology category contains 269 questions and can be combined with specific organ systems for targeted review.

Examples include:

• Cardiovascular physiology
• Pulmonary physiology
• Renal physiology
• Gastrointestinal physiology
• Endocrine physiology
• Neurophysiology
• Reproductive physiology

Behavioral Science & Biostatistics

This edition includes:

• Behavioral Science — 252
• Biostatistics — 120

These categories can support preparation involving:

• Behavioral health
• Epidemiology
• Study interpretation
• Statistical concepts
• Communication
• Population health principles

USMLE currently lists Biostatistics & Epidemiology/Population Health and Communication and Interpersonal Skills among the assessed Step 1 content areas.

Biochemistry and Genetics

The QBank includes:

• Biochemistry — 158
• Genetics — 107

These foundational subjects can be integrated with clinical systems and disease mechanisms rather than studied only as isolated factual material.

Immunology

The 132-question Immunology category provides focused practice in immune mechanisms and their relationship to disease.

Topics can be integrated with infectious disease, hematology, rheumatology and multisystem concepts.

Study Anywhere, on Multiple Devices

Because the QBank is browser-based, you can access it from supported devices including:

• Phone
• Tablet
• Laptop
• Desktop

This provides flexibility for short practice sessions as well as longer dedicated study blocks.

An internet connection is required because the QBank operates online.

Suggested Step 1 Study Workflow

A practical study sequence is:

1. Select a Subject or System

Choose the material that matches your current study plan.

2. Create a Customized Test

Build a focused question session.

3. Answer Questions Before Reviewing Explanations

Use each question as an active recall exercise.

4. Review the Explanation Carefully

Understand both the correct concept and the reasoning that makes competing options inappropriate.

5. Identify Weak Areas

Use your test history and scores to determine where additional review is needed.

6. Repeat Targeted Questions

Return to difficult topics during later sessions.

7. Progress Toward Broader Mixed Tests

After focused review, combine several subjects and systems to practice integrated reasoning.
