Question Bank

This is the future home of the world's largest and most comprehensive free board review question bank.

Introducing the World Medical School Questions Bank (WMS-–QB)

The goal of this initiative is to create the world's largest and most comprehensive board review question bank offering free, open, and unlimited access to online visitors from all around the world.

We are not just being optimistic, but realistic as well. For it is our firm  conviction that if medical students all over the world were to unite  in posting original board review style questions to this global database, we would without doubt be well on our way to do better than  the best paid-subscription question banks out there.

Our database has already begun to fill up and we rely on student volunteers to perpetuate the addition of new and diversified questions of varying calibre and difficulty.

Volunteering in this regard evidences an enduring show of support on your behalf to prospective, current, and returning medical students, aspiring physicians, and medical practitioners worldwide and thus poses an ideal method by which to leave your mark on the global medical community. But that’s not all, through your contributions to the World Medical School Questions Bank (WMS-QB), you are bound not only to be hailed an official contributor of a rocketing multiethnic world-wide medical institution but are also in fact better preparing yourself for sitting for the USMLE Step 1 and Step 2 Clinical Knowledge and Clinical Skills exams as well.

At some point down the road, World Medical School hopes to publish all its questions in one application for ease of access to all students, and of course, at zero cost.

Question Submission Guidelines

All submitted questions should abide by the following protocols:

1)    Questions should be of standard quality. In meeting the set standards for inclusion with the WMS–QB, questions:

          a.    Must resemble board review style questions or in other words should compare with questions appearing in the USMLE exams in order to ensure quality and consistency of content with respect to USMLE exams.
          b.    Must pertain strongly to subjects of the USMLE Step 1 and 2 exams with minimal divergence,
          c.    Must be written in clear and comprehensible English and properly cited where and when necessary.

2)    All questions must be submitted in multiple choice format bearing five possible answer choices labelled from A to E.

3)    All questions should be submitted along with a lengthy explanation of all five answer choices displayed, clearly elucidating which choices are wrong, which are correct, and why.

4)    Questions may cover any of the many topics covered by the USMLE exams (click here for a list of topics covered by the different USMLE exams) and should be categorized as pertaining to either Step 1 or Step 2 Clinical Knowledge questions.

5)    Images, figures, or diagrams that serve to facilitate, enhance, or expand on submitted questions are welcomed on the sole premise that they be properly cited and/or referenced. Please only use images found on Wikipedia or other verifiable Public Domain or Creative Commons licensed images to ensure copyright compliance.(See sample question 3 for an example).

6)    All questions are to be submitted on the form below.


Note to Contributing Authors

All names of authors having contributed to the WMS–QB will be credited on our authors’ page as follows:

1)    Contributing Authors: Names of volunteers having successfully submitted at least one question of good standing.
2)    Junior Qbank Authors: Names of volunteers having successfully submitted 10-19 questions of good standing.

3)    Senior Qbank Authors: Names of volunteers submitting 20 questions or above of good standing including a space for further acknowledgement of their unique picture portraits.

Authors presenting persistent interest and volunteer efforts in building the WMS–QB shall be automatically considered for administrative posts at World Medical School.


In closing, World Medical School looks forward to a day were just about anyone anywhere with an internet connection can log on to an online webpage and be transferred to a limitless supply of learning resources for their personal and business-oriented career development, all at zero cost.

With all our efforts combined there is nothing we can’t do.

We leave you with the mesmerizing words of American Cultural Anthropologist Margaret Mead:

“Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has.”

Sample Questions

1.    A 40 year old Asian female presents to the emergency complaining of a swelling that slowly increased in size since she returned from Africa two weeks ago. On examination, you find a nodule that emits bubbles through a central pore while submerged in water.
What is the causative organism?

A.    Pediculus humanus
B.    Tunga penetrans
C.    Sarcoptes scabiei
D.    Cordylobia anthropophagi
E.    Ancylostoma braziliense

Explanation: The symptom is typical of Furuncular Myiasis, which is caused by the larvae of Cordylobia anthropophaga, the African tumbu fly. It deposits its eggs on drying laundry and these hatch once in contact with the body and penetrate the skin. The other choices are wrong since they lead to other cases: Sarcoptes scabiei causes Scabies; Pediculus humanus causes Pediculosis; Ancylostoma braziliense causes Cutaneous Larva Migrans; and Tunga penetrans causes Tungiasis.

Please mention: “This is intended to be a Step 1 question. Topic: Microbiology (parasitology)”


2.    A 54 year old male presents to the emergency room complaining of chest pain and shortness of breath. An electrocardiogram shows ischemia of the posterior myocardium.

Which leads are affected primarily?

A.    I and aVL
B.    II,III, and aVF
C.    V1 and V2
D.    V2-V4
E.    V5 and V6

Explanation: The only leads that can show the posterior myocardium are V1 and V2 placed directly to the right and left of the sternum. Leads I and aVL shows the left side of the heart; Leads II,III,aVF reflect the inferior wall of the heart; while V2-V6 reflect the left lateral side.
Please mention: “This is intended to be a Step 1 question. Topic: Cardiology”



3.    A 19 year old female has complained of recurrent attacks of tachycardia and palpitations. After finishing the physical exam, you find her to seem fine except for the tachycardia. An EKG (check image) was taken, which shows some abnormality.

Which of the following is the most likely diagnosis for this patient?

A.    Anxiety reaction
B.    Floppy mitral valve
C.    Wolff Parkinson White syndrome
D.     Clockwise rotation of the heart
E.    Sick sinus syndrome

Explanation: The first and fourth waves in the EKG show a short PR interval and a slurred proximal limb of the QRS complex known as the delta wave. This is typical of the WPW syndrome.

Don’t forget that by doing this, you are not only studying the information for the steps (or remembering them) or adding a good booster to your CV, but you are also doing a precious favor for all medical students all over the world whom a big group of them cannot afford the expensive question banks available in the market.

That’s all for now, if you have any questions please let me know.
