532 Views
Most medical students will take NBME Clinical Science Subject Exams, or “shelf” exams at the end of a clinical rotation. Depending on your medical school, there may be different score or percentile cutoffs for passing and honors grading. While the grading system at each medical school is unique, a 90th percentile score on a shelf exam is widely held as excellent. In this post, we’ll explore the strategies and tips you need to achieve a 90th percentile score on the psychiatry shelf exam.
First things first, let’s review the exam format and grading. Similar to other shelf exams, the psychiatry exam is 110 questions to be completed in 2 hours and 45 minutes. You will take the exam in one block, there are not separate blocks like USMLE Step 1 or 2 exams. According to Texas Tech School of Medicine, a 90th percentile score corresponds to approximately 91-92% correct answers. If you are working towards a 90th percentile score, you should be aiming for higher than 92% correct.
The most important factor to achieving a high percentile score on your psychiatry shelf is creating a study plan early that works with your clinical rotation schedule. Once you know your clinical site location and hours, take a moment to review the time you have to study and the resources that you have available to you. You should aim to complete the psychiatry shelf question Uworld Qbank about 1-2 weeks before your clinical rotation ends with time to re-do incorrect questions. Incorporate spaced repetition into your study schedule using tools like Anki to reinforce your learning. Take and review all available practice NBME exams before your exam (there are currently 3 available).
Maximize your patient interactions during clinical rotations by actively learning from each case. Some questions you should ask yourself with each patient case:
- What is my patient’s diagnosis? Which speicifc symptoms do they exhibit and which diagnostic criteria do they fulfil (ex: SIGECAPS for depression, DIGFAST for mania)?
- What medications is my patient taking? What class of medicaitons does this medication belong to? What side effects are we monitoring for in the patient?
- If in-patient: why is this patient hospitalized? What needs to happen before they can go home?
- If out-patient: how is this person functioning? What kinds of symptoms or behaviors are impairing their daily function?
Outside of your clinical time, be consistent with your qbank questions and spaced repition. Pay special attention to the following high yield concepts during your clinical rotation and study time:
- Psychiatric medications: indications, mechanism, monitoring, and high yield side effects
- Ex: antipsychotics – extrapyramidal symptoms and treatments
- DSM 5 criteria for psychiatric diagnoses
- Psychiatrics disorders vs normal development or functioning (ex: developmental separation anxiety vs separation anxiety disorder, normal memory changes in aging vs dementia)
- Symptoms of substance use disorder and withdrawl, when medication therapy is appropraite
- Signs that a patient may or may not have decision making capacity
- Differentiating between psychiatric and neurological disorders (ex: major depressive disorder vs hypothyroidism)
- Recognizing and treating psychiatric emergencies: seratonin syndrome vs neuroleptic malignant syndome. It is also helpful to consider these both in the context of malignant hyperthermia and how you would distinguish them.
