COMLEX CDM is a relatively new part of the COMLEX Level 3 exam. CDM is short for "Clinical Decision Making." Essentially, you will be presented with a clinical case and you will need to make decisions about performing a physical exam, ordering labs, interpreting labs, ordering imaging, interpreting imaging, and providing treatment. Treatment could include things like medications, antibiotics, surgery, consultations, fluids, to name a few. 

There are two different types of answer types when answering questions: There is the multiple choice answer where you have a number of choices and you can order a specific number of answers (i.e. like ordering 3 of 15 answers). The second type of answer is the short answer or fill-in-the-blank answer. This is where you can type anything in the answer. COMPLEX CDM is very specific on how they wish for the fill in the blank to be formatted. Check out our post on how to correctly fill out the fill-in-the-blank answers. There are quite a few rules that the COMLEX has posted. 

Each COMLEX CDM case has 2-4 questions on each case and can ask anything that has been listed above. We go over all aspects of a case so that you can answer any of the questions that can be asked for a specific case, so our cases have more questions that you will typically see on the COMLEX. Our cases on cdmcases.com will have between 4-8 questions to cover all aspects of the case which include the appropriate part of the physical exam that should be ordered, the appropriate lab work and imaging, appropriate treatment, and appropriate follow-up and required consultations.

If you would like to try out our COMLEX CDM Cases for yourself, you can go here and sign up for a demo to try out 2 free CDM cases. We ask that you take some time to try it out and learn how the CDM portion of the test works.

For those looking for COMLEX Level 3 CDM Cases, look no further. We have 100+ cases that have an interactive simulator that will help you master the CDM portion of the COMLEX Level 3 exam. It goes through the different types of questions including the fill in the blank questions and the multiple choice questions. Feedback will be given based on your responses at the end of the case. 

If you would like to get feedback after each question, there is an option to turn this on in our practice mode option. We let you try out 2 of our cases for free before purchasing. We feel the once you try out our COMLEX Level 3 CDM Cases, that you will know that these are high quality cases that will help you perform well on the COMLEX level 3 on test day. 

Other companies will only offer a few cases to practice on. There are approximately 26 Clinical Decision-Making (CDM) on test day. There are 8 sections on the COMLEX test and 2 of them are dedicated to CDM cases. This means that the CDM is 25% of your grade.  

This is a significant portion of your grade that you should not neglect. This can be the difference between passing and failing. The software takes some getting used to, so you should be doing many many practice cases. No one offers as many cases to practice for the CDM portion of the exam.

We have 100+ COMLEX Level 3 CDM cases that will go through the most commonly seen cases on the COMLEX. It will go through physical exam findings, ordering tests, data interpretation, generating a diagnosis, and treatment. 

Treatment includes prescribing medication, planning follow-up, and counseling.

Each cases will have 2-4 questions. We have more questions in our cases because a clinical case may focus on a particular part of the case and not others. We include all parts so that you will be prepared for any COMLEX Level 3 CDM cases question in regards to a specific case.  

There will be 26 cases on the morning of the second day of the COMLEX test. There will be 13 cases followed by a 10 minutes break and then another 13 cases for a total of 26 cases. Each case will have 2-4 questions for a total of approximately 70-80 questions total. The multiple choice questions for the rest of the test will be 420 questions (6 sections of 70 multiple choice questions = 420 questions), so with the CDM cases there will be a total of 490-500 questions. 

As this is 2 sections out of 8, this will be approximately 25 percent of your grade, so it is important to study hard for the CDM portion of the exam. We ask that you try our free 2 cases which are located here and find out for yourself that our COMLEX Level 3 CDM questions are going to be an essential part of your studying plan to do well on the COMLEX level 3 exam.

What are CDM Cases?

CDM Cases are short for Clinical decision making cases. This is a relatively new part of the COMLEX Level 3. Essentially, there will be a case introduction with a clinical scenario such as a patient presenting with chest pain. Some things that the case can ask you in the CDM Cases is what physical exam to perform, what imaging to get, what medication to prescribe, the disposition of the patient (discharge home or admit to the hospital), and the diagnosis for the case. 

There will be 26 of these cases which will take 3.5 hours on the morning of the second day of the COMLEX Level 3. The best strategy to do well on these cases is to know everything about that particular case so that you will be prepared for anything that the exam will throw at you. Knowing the correct test, imaging, medications, and diagnosis is what will make you do well on a particular case. 

The key to doing well on the CDM Cases portion of the test is to practice, practice, practice. The software can take some getting used to, particularly the fill in the blank (the test calls it short answer responses). This has quite a bit of rules which you will need to be familiar with prior to taking the test.



Try out out demo which you can try two free cases which is located here. Thanks for reading.

Rules for short answer (fill in the blank):

#1 - If giving a drug, give drug name, not classes (example: give hydrochlorothiazide rather than "antihypertensive").

#2 - If giving a drug, give the route of the drug : Oral (by mouth), inhalation, sublingual, intravenous, intramuscular, subcutaneous, intradermal, topical) Try not to abbreviate.

#3 - Imaging studies: Must include anatomic site (example: Chest xray instead of xray)

#4 - Avoid or limit use of abbreviations due to lack of standardization. We accept some standard abbreviations, but it would be safer to spell it out and not abbreviate on the test!

#5 - Protocols will not be accepted as correct because they are often not universal.

#6 - Urgency: Include “stat” when a procedure or diagnostic test is needed within 30 minutes, regardless of clinical setting, including the emergency department.

#7 - Referrals and consults: If the correct plan of action requires a specialty referral and/or consultation, in addition to the type of specialist you must specify the appropriate procedure or management step the specialist will perform (for example, “refer to psychiatry for cognitive-behavioral therapy”).

Note that just like in the real test, there might be 2 phrases required in a fill-in-the-blank answer. As with the example above with referral to psychiatry, the first phrase that will be matched is "psychiatry" and the second phrase that will be matched is "cognitive behavioral therapy." In the feedback section, there will be a marker "Additional phrase required" which will show you the second phrase that must be matched.

Another example of 2 phrases that must be matched is with fill in the blank medications which require the route of administration. The first phrase would be the medication such as lisinopril. The second phrase would be the route which would be oral or by mouth or PO (though try to limit abbreviation usage). The correct response would be lisinopril by mouth.

How does the Extended Multiple Choice Functionality work on the CDM Portion of the COMLEX?

This is a lot more intuitive then the fill-in-blank or short answer type questions. The question will tell you how many options you can select. There is a built in stupid test in this type of question. If you select more options than they tell you can, you will GET A ZERO for the entire question, so DONT DO THIS! For example, if they say you can select up to 5 of the 15 options, and you select 6 options, then no matter what you have selected, you will get a zero for that question. If you did this, then you won the stupid test. This was very stupid thing to do. It's easy not to do this, so just don't do it. You select the BEST answers that would pertain to the question.

That's pretty much it. There isn't much else to it. Select the best responses, make sure that you don't go over the allowed responses, and make sure you read all of the options before you go to the next question.

If you would like to try out these types of questions for yourself, try out 2 free cases here! Thanks for reading.

There are 26 CDM Cases on the COMLEX. There will be 70-80 questions total. Each case has 2-4 questions each. This will take 3.5 hours (2 sections). There are a total of 8 sections, so 2/8 = 25% of your grade. This means that you should not neglect this part of the test as it is worth 1/4 of your total grade which can make or break your score if you don't very well on this section.

We ask that you try out our free 2 cases here, and you will see that this will help you prepare for the COMLEX CDM portion of the exam. 



Thanks for reading.

There are 26 CDM Cases on the COMLEX which means that there will be 70-80 questions total (some tests have more or less questions depending on the draw from the Qbank). Each case has 2-4 questions to answer.

The CDM portion will take 3.5 hours (2 sections). There are a total of 8 sections on the entire COMLEX, so 2/8 = 25% of your grade.

For Extended Multiple Choice, partial credit can be awarded if you answer some but not all of the correct answers (for example, the question has 5 correct choices, and you select 4). You will receive a zero if you select more choices than allowed (for example, you select 7 answer choices when only 6 were allowed). You will receive a zero if you select an answer choice that would harm the patient.

All answers are weighted equally (one question is not worth more than another question). The Short Answer responses will get a point if you enter the correct response. You will get a zero on the short answer response if you put more than 1 response in a single box (for example: IV fluids and administer lisinopril). You will also get a zero for that question if you enter a response that could harm the patient.

This is an important part of Level 3, so this section should be taken seriously as 1/4th of your total grade which can make or break your score. We hope that you will take this seriously and study with us. We have over 100+ cases that will allow you to study and be confident on test day to rock this section.

Failed COMLEX Level 3

We all know how disappointing it is to fail a major examination, particularly when you have failed COMLEX Level 3. All those hours spent studying along with the feeling that you thought you wouldn't have to study certain material ever again. 

Some students have a specific area that have led to fail the COMLEX Level 3. A typical area that leads students to fail the COMLEX level 3 is the Clinical Decision Making (CDM) section. The main reason is that the format of the CDM questions are unfamiliar leading some students to do poorly enough to fail the COMLEX level 3. 

At cdmcases.com, we focus on this particular section of the COMLEX level 3. We have 140+ cases that go through all of the commonly seen CDM cases that will help you be prepared for the CDM portion of the COMLEX Level 3. We have internal medicine, psychiatry, neurology, osteopathic manipulative medicine, and emergency medicine cases.

We added a new user interface to CDMCases.com. We knew that our user interface was vanilla and very utilitarian. We have redesigned everything and made it much more visually appealing and keeping the same features and even added some new features. Here is a screenshot of what the case selector:

Some new features:

• Filter cases by Category
• New "Card Style"
• Hide Completed/Incomplete Cases
• New "Tags" feature that you can narrow down case by keyword such as "chest pain."
• Added new Theme which include dark mode, beach theme, and jungle theme.
• Ability to print your receipt
• Ability to hide cases
• New Report Card Feature

Report Card Feature:

The Report Card Feature is helpful to determine which categories and/or specific cases that need the most work prior to taking the test. This can be helpful, so you can focus on categories such as Pediatrics prior to test day. This is helpful to compare your progress to the average of all of users to determine how you are faring in comparison to your peers. This can help you determine when you are ready to tackle the real test. Here is an overview of what the report card feature goes overs:

• First Case Attempts versus All other users average score
• 10 worst performing cases
• 10 best performing cases
• First Attempt vs Best Attempt by Case
• Average Attempt by Category
• Performance over Time

We have added Osteopathic Manipulative Medicine (OMM) cases. The OMM cases are minimal on the real COMLEX Level 3, but it's still important to be prepared for the rare OMM case that could appear on the Level 3 exam. We have included some of the commonly seen Osteopathic Manipulative Medicine (OMM) cases. We hope that you enjoy them!

We have released our beta version of CDMCases.com! We have completed 75 cases and are going to be doing the beta version until we reach 100 cases. Our goal is to reach 140 cases by the end of the year. The beta version means that you might encounter some minor issues that still need to be fixed before we release the full version. In compensation for trying our beta version, it will only be $1.

Why charge a $1? This is simple psychology: if you are willing to pay even a token amount, these people tend to be more involved in the process. This makes the process cleaner. We have a limited amount of beta testers, so it is a first come first serve process.
