The USMLE Step 2 CK Clinical Knowledge exam is multiple-choice and designed to determine whether examinees possess the medical understanding and knowledge of clinical science essential for patient care under supervision.

The Step 2 CK exam is available for students to sit in London.

USMLE Step 2 CK Exam Overview

• 9 hours (including a one hour break)
• 370 questions. 46 questions in 8 one hour “blocks”.

Step 2 CK questions will NOT be grouped by subject within blocks. So you won't find a section devoted to pediatrics for example. The ordering of items can therefore present you with the challenge of switching from thinking about one subject to another, without skipping a beat.

USMLE Step 2 CK Question Formats

There are two multiple-choice formats used on Step 2 CK:

• Single best answer
• Single answer matching

Most questions describe a patient and want you to recognize the underlying mechanism of the disease, order diagnostic studies, propose a diagnosis, or initiate treatment.

USMLE Step 2 CK Scoring

The minimum passing score on the Step 2 Ck is 189. To achieve a passing score, you normally need to answer between 55% and 65% correctly.
