Our Ranking Criteria

In selecting the best COMLEX-USA prep courses for this list, we considered several important factors. Most importantly, we’ve selected those that have proven track records of successfully helping students score well on their exams. Additionally, we looked at courses that offer multiple format options, as well as personalized instruction and tutoring for students who might need extra help.

Flexible scheduling and adaptable formats

Many osteopathy students keep busy schedules that involve coursework and practical work in addition to studying for their COMLEX-USA exams. Because of this, it’s important that prep courses are able to offer flexible scheduling and adapt to the formats that work best for students.

Personalized instruction

Having access to extra tutoring or personalized instruction is vital for a lot of students who are preparing for exams. If you’ve previously taken the test and need extra help or if you’re keeping a busy schedule and feel overwhelmed with studying independently, personalized instruction is often the best way to ensure success when it comes time to take your COMLEX-USA test.

COMLEX-USA Frequently Asked Questions

What are the important dates for taking the COMLEX-USA?

COMLEX-USA tests are administered at testing centers. Each test is offered almost daily, including on Saturdays, and testing sessions are a total of four hours. Tests can be booked once students are provided with registration details from the National Board of Osteopathic Medical Examiners (NBOME), and while there aren’t deadlines for registration, you do need to provide at least 30 days’ notice to reschedule or cancel a test without penalty.

Are there accommodations for disabilities?

The NBOME provides accommodations for disabilities when they’re requested in advance. It typically takes up to 75 days for the NBOME to approve and process accommodation requests so it’s important to make requests as soon as you know they’re needed. Accommodation requests must be submitted with supporting documentation, including a personal narrative explaining the impairment and an evaluation from a physician or other qualified professional.

Where can I find practice tests?

Practice tests can often be obtained from the test prep courses listed above. Additional practice tests can be found online at the NBOME’s website.

How early should I prep?

How many practice tests should I take before the actual exam?

It’s important to use practice tests to monitor your study progress and to determine what areas you may require extra support in. It’s recommended that you take practice tests regularly in the months leading up to your exam date with most students taking at least one practice test every one to two weeks.

How long are most COMLEX-USA prep courses?

The length of COMLEX-USA prep courses varies in length, with some offering boot camp style prep in just a few weeks and others offering intensive prep over several months to years.
