Step 2 CK Practice Exams: Which NBME to Take and When
A plain order for the Step 2 CK NBME forms and the Free 120: what to take first, what to save for the end, and how to review each one.
· 6 min read · IvyMed
The short version
- Start with an older form for a baseline and save the newest forms for your last weeks
- Space practice exams one to two weeks apart in dedicated and take them timed, in one sitting
- Most Step 2 CK misses are management, not diagnosis, so review the next step, not just the disease
- Your shelf weaknesses are a head start: they usually show up again on CK
The practice exams you can take
The NBME sells Step 2 CK self-assessments (forms 8 to 15 are the ones students use now), and the USMLE posts a free sample test, the Free 120. Newer forms are built most like today's exam.
Each form has its own guide on our blog with how hard it is, how long its questions run and which systems it tests most.
A simple order that works
Spread your forms across dedicated like this:
- Baseline: one older form before or right at the start of dedicated.
- Middle weeks: one form every one to two weeks, timed and in one sitting.
- Last two to three weeks: the newest forms, when you want the closest match to the real exam.
- Final week: the Free 120 as a last check, not a learning tool.
How to review a Step 2 CK form
On Step 2 CK the diagnosis is usually the easy part. Most misses come from choosing the wrong next step: testing when the patient needs treatment now, or treating before the diagnosis is confirmed.
For each miss, write down the clue that made the right next step right, and the reason the answer you picked was wrong for this patient.
Use your shelves as a head start
If you are coming off rotations, your shelf scores already tell you where to start. The subjects that were hardest on the shelves tend to be the ones that cost points on CK.
Questions students ask
- Which Step 2 CK NBME should I take first?
- Start with an older form for a baseline. Save the newest forms for the last two to three weeks of dedicated, when you want the closest match to the real exam.
- Which Step 2 CK NBME is the hardest?
- Our difficulty ranking scores every Step 2 CK form from its questions (reasoning steps, hidden diagnoses, how indirectly it asks), so you can see which ones run hardest before you take them.
- How many practice exams should I take for Step 2 CK?
- Many students take one form every one to two weeks across dedicated plus the Free 120 at the end. More forms only help if you have time to review each one well.
