How to Prepare for COMLEX Level 1 Without Overstudying

Preparing for COMLEX Level 1 is a significant milestone for osteopathic medical students. With the recent transition to a pass/fail scoring system, the emphasis has shifted from achieving a competitive score to simply passing while developing strong clinical reasoning skills that will set you up for success in the hospital and on Level 2-CE. However, students often struggle with how much to study, which resources to use, and how to balance studying with other responsibilities. This guide provides an efficient strategy for preparing for COMLEX Level 1 without falling into the trap of overstudying.

Understanding COMLEX Level 1

COMLEX Level 1 primarily assesses your understanding of foundational biomedical sciences with a strong focus on osteopathic principles and practice (OPP). It consists of multiple-choice questions designed to test your ability to apply knowledge rather than simple memorization. The exam is divided into two four-hour sessions with a total of 352 questions, requiring endurance and focus.

How Hard Is It to Pass COMLEX Level 1?

The difficulty of COMLEX Level 1 varies among students, but the key to passing is consistent preparation with a focus on high-yield material. Since the exam is now pass/fail, students should prioritize comprehension over exhaustive review. The key challenge lies in the broad scope of material tested and the need to integrate osteopathic principles into clinical scenarios. Finding the balance between knowing enough to pass and knowing enough to be clinically proficient can be difficult now that the examination is pass/fail. 

What Percentage of People Fail COMLEX Level 1?

Historically, the first-time pass rate for COMLEX Level 1 has been above 90% for first time test takers in accredited osteopathic schools. However, those who fail often do so due to poor preparation strategies rather than a lack of intelligence or effort. Additionally, students who fail the test on their first attempt, often have lower pass rates overall (i.e., if you fail your test on the first attempt, you are less likely to ever pass the test). However, even 75 to 85% of repeat test takers ultimately do pass Level 1. Identifying weaknesses early and adapting your study approach is crucial to ensuring success. Below are data regarding the pass rates for COMLEX Level 1 over the past few years:

Which Is Harder: USMLE or COMLEX?

Both exams are challenging, but they differ in format and focus. USMLE Step 1 is often regarded as more detail-oriented in the basic sciences, while COMLEX Level 1 incorporates some of this content, but also integrates osteopathic manipulative medicine (OMM). Many DO students find COMLEX more difficult due to the additional osteopathic content which often is not prioritized in their studies, while others struggle more with the detailed molecular and cellular mechanisms emphasized in USMLE. Many osteopathic students ultimately choose to take both COMLEX and USMLE examinations, and it is important to recognize that there is a significant amount of content overlap between the two tests.

Strategic Study Plan

1. Set a Realistic Study Timeline

Avoid cramming by developing a structured study plan. Most students prepare over a 4–8 week dedicated period, but studying efficiently during your preclinical years can reduce the need for excessive review.

• First-pass learning: Focus on understanding fundamental concepts throughout your preclinical years. This way, when you return to studying for your dedicated period, you will be relearning the specific details to bolster your comprehension of the material, rather than trying to understand a concept and learn the specifics at the same time.
• Dedicated study period: Allocate 4–8 weeks for review and practice questions. The amount of time students are studying overall has decreased now that the test has become pass/fail. 
• Consider taking a diagnostic practice test: It can be helpful to start with a practice test at the beginning of your dedicated period to determine how close you are to passing. This information can then be used to make an informed decision about how many weeks you will need to dedicate to Level 1 studying.
• Daily schedule: Students study around 6–12 of hours of focused study per day with built-in breaks. The amount of studying is extremely variable and again depends on how much time you need.

Sample Study Schedule:

• Morning: 2-3 hours of question bank practice + review explanations
• Midday: 2 hours of focused topic review (pathology, physiology, pharmacology)
• Afternoon: 2-3 hours of OMM and more question bank practice
• Evening: Light review, flashcards, or videos on weaker topics

2. Choose High-Yield Resources

Avoid resource overload. There are more resources available on the market than ever before and you will not be able to go through them all. We recommend sticking to a few high-yield resources to improve retention and prevent burnout. Some of our essential resources are listed below

• • UWorld & TrueLearn Question Banks: Probably your most important resources – these question banks are the most effective resource for active learning and preparing you for test day.
  • First Aid for Step 1: Provides an overview of key topics – while this book was written primarily for USMLE Step 1, there is a lot of overlap between the two exams.
  • Sketchy Micro and Pharmacology: Ideal for microbiology and pharmacology – these videos have stood the test of time and are great for visual learners.

• Pathoma: A very high yield review course on all things pathology. There are videos and a short textbook to provide you with a fast overview on the most important pathology topics.

• Boards and Beyond: A good course that can help you develop your understanding of the foundational sciences – can be used as a supplement to or replacement for First Aid.
• Osmosis: Useful for visual learners – while it will be challenging to get through all of the videos they have available, this resource can serve as a great option for targeted learning on concepts you struggle with.
• Comprehensive Osteopathic Medical Self-Assessment Examination (COMSAE): It will be crucial for you to take multiple COMSAE examinations over your dedicated study period to ensure that you are comfortably passing before test day.

3. Optimize Question Banks and Practice Exams

Why Use Question Banks?

• Helps reinforce active learning.
• Improves test-taking skills.
• Identifies weak areas.
• Simulates what you will tackle on test day.
• Develops your stamina and time management.

How to Use Question Banks Efficiently:

• Start questions early rather than saving them for later. Aim to complete 100% of the questions in your bank.
• Focus on learning from explanations rather than memorizing answers. You should strive to not only look for the correct answer, but to also understand why the incorrect answers are incorrect.
• Do timed and randomized practice questions to simulate real exam conditions. It is not necessary to do timed and randomized questions 100% of the time. However, as you get closer to test day, it will be important for you to incorporate more timed and random questions like you will see on test day.

Recommended Practice Exam Strategy:

• Take a COMSAE exam 4–6 weeks before test day to assess your baseline – this can help you determine how much time you need to study.
• Schedule 2–4 full-length practice tests during your study period.
• Use NBOME’s free resources and practice exams to familiarize yourself with question styles.
• Review incorrect questions thoroughly to understand patterns of mistakes. Focus on not only understanding what material you do not know, but also, if there are test taking strategies you can better employ.
• Focus on applying concepts to similar scenarios rather than memorizing answers.

4. Focus on High-Yield Topics

Avoid wasting time on low-yield material. Prioritize:

• Physiology & Pathophysiology: Foundation for disease mechanisms.
• Microbiology & Pharmacology: High-yield for memorization-heavy content, often great for flashcards
• Osteopathic Manipulative Medicine (OMM): Make sure to know techniques and Chapman’s points.
• Biostatistics & Ethics: Often overlooked but frequently tested – this material will show up on future COMLEX and USMLE examinations so try and master this early
• Clinical Decision-Making: Many questions test how you would approach patient care in a real-world scenario, so practice applying knowledge. This topic will become more apparent on Level 2-CE and Step 2 CK but can show up on Level 1 and Step 1.

5. Avoid Overstudying

Overstudying can be just as detrimental as under-preparing. Many students fall into the trap of endless review cycles, diminishing returns, and burnout. Here’s how to avoid it:

• Set daily study limits: Stick to a set number of hours of focused study per day and incorporate some time off – whether this be a full day or half day.
• Use active recall: Instead of passively re-reading notes, engage in active recall with flashcards, self-quizzing, or teaching concepts to others. Try and use multiple different forms of study material.
• Implement spaced repetition: Revisiting topics over intervals helps long-term retention better than cramming.
• Take breaks: Use the Pomodoro technique (50 minutes study, 10 minutes break) to maintain focus.
• Prioritize sleep and exercise: Cognitive function declines with sleep deprivation. A well-rested mind retains information more effectively.
• Avoid excessive note-taking: Focus on summarizing and reviewing rather than writing down everything.

By maintaining a structured but balanced approach, you can ensure you’re absorbing the most important material without burning out.

6. Balance Studying with Other Responsibilities

Medical school demands extend beyond board preparation. To maintain balance:

• Keep up with clinical responsibilities.
• Allocate time for relaxation and hobbies.
• Use study groups for efficiency but avoid unfocused discussions.
• Avoid comparing your progress with peers—everyone has a unique learning style. There is more than one way to pass this test!
• Develop time management skills to efficiently balance rotations, coursework, and board prep.
• Set realistic goals and track progress to ensure steady improvement without unnecessary stress.

7. Reach Out for Help: Consider a Tutor

8. Exam Day Strategies

To perform well on test day:

• Get adequate sleep the night before.
• Eat a balanced breakfast to sustain energy.
• Use time wisely—flag difficult questions judiciously, and return to them later.
• Stay calm—anxiety can negatively impact performance.
• Follow a pre-exam routine to minimize stress and boost confidence.
• Trust your preparation—avoid last-minute cramming, which can cause confusion.
• Pace yourself—don’t rush through questions but also avoid overanalyzing.
