Quality Is Our Obsession
We know COMLEX Level 1 questions better than anyone!
Anatomy of the COMLEX Question
Every COMLEX Level 1 practice question is written to align with the official COMLEX Level 1 blueprint. Our rigorous editorial process, backed by expert analysis and real-time learner feedback, ensures accuracy, appropriate difficulty, and exceptional quality across the entire question bank. Our attention to every detail helps you build the confidence and knowledge needed to excel on exam day.
Question Stem & Lead-In
We design every item to mirror the actual COMLEX Level 1, down to every detail of the question stem and lead-in. With a strong emphasis on 2nd and 3rd-order thinking, our questions challenge you in the exact format you’ll encounter on exam day—so you’re fully prepared to succeed.
Answer Choices
We use best practices to craft answer choices that are plausible, consistent in length and format, and designed with a clear “best” option. Through rigorous psychometric analysis, we fine-tune each question to maintain appropriate difficulty.
Answer Explanations & Bottom Lines
To maximize the full power of the “testing effect,” we craft high-yield answer explanations for both the correct and incorrect answer choices. To make learning even more durable, we incorporate figures, charts, and diagrams to reinforce difficult concepts. When reviewing TrueLearn explanations, it’s common to pick up as many as 10 additional learning points that can give you an edge on test day. For quick review, each question also includes a Bottom Line that concisely summarizes its key takeaway.

Get To Know The COMLEX Level 1 Exam
Students should be prepared for a full day of testing. The exam occurs in 2 four-hour sessions. Students are also allotted up to 60 minutes of break time throughout the day.
Level 1 contains 352 multiple-choice questions broken into eight sections of 44 questions each. Students can prepare for this volume by creating practice tests within their SmartBank and incrementally increasing the number of items each day leading up to the exam.
For Level 1, the minimum passing score students must achieve is 400. As of May 2022, test-takers will not receive an actual score, rather they will see a pass/fail designation with a performance profile for each content area.
Students should prepare for a minimum of 11% of the 352 questions to cover osteopathic manipulative medicine (OMM) directly, which will increase to 12% on May 7, 2024 at the start of the 2024-2025 testing cycle. Plus, OMM is integrated through all areas of the exam, reflecting how osteopathic principles and practices permeate osteopathic medicine.
COMLEX Level 1 is typically taken towards the end of your second year of medical school. Most students start preparing for the exam shortly after the school year begins and subscribe to a question bank 6–9 months prior to test day.
