The United States Medical Licensing Examination (USMLE) Step 1 is a standardized test that assesses a medical student's knowledge of basic science concepts and their application to clinical medicine. The exam is one of three components required for medical licensure in the United States and is typically taken by students after their second year ...
USMLE Step 2 CK ("Clinical Knowledge") is a nine-hour-long exam that represents the second part of the United States Medical Licensure Examination. [1] It assesses clinical knowledge through a traditional, multiple-choice examination divided into eight 60-minute blocks, each containing up to 40 questions, as well as an hour of break time. [ 2 ]
In clinical practice, post-test probabilities are often just estimated or even guessed. This is usually acceptable in the finding of a pathognomonic sign or symptom, in which case it is almost certain that the target condition is present; or in the absence of finding a sine qua non sign or symptom, in which case it is almost certain that the target condition is absent.
Alternatively, post-test probability can be calculated directly from the pre-test probability and the likelihood ratio using the equation: P' = P0 × LR/(1 − P0 + P0×LR), where P0 is the pre-test probability, P' is the post-test probability, and LR is the likelihood ratio. This formula can be calculated algebraically by combining the steps ...
Materials allowed within the exam room are extremely limited and most require prior approval, including medical equipment. Examinees are on video surveillance during the examination. The test is available throughout the year to the examinees. Since 2014 USMLE Step 3 can be taken on two non-consecutive days, instead of two consecutive days. [2]
The probability of having a specific range value, t, can be determined by adding the probabilities of having two samples differing by t, and every other sample having a value between the two extremes. The probability of one sample having a value of x is (). The probability of another having a value t greater than x is:
The three-digit score is based on a theoretical maximum of 300, but this has not been documented by the NBME / FSMB. Previously, a 2 digit score was also provided, but has since been eliminated. The two-digit score was normalized to the three-digit score such that a 75 was equal to the minimum passing score (currently 194) for the USMLE Step 1. [1]
