How Many Questions are on the USMLE Step 2?

The test consists of a one-day, 9-hour examination and usually is harder than the remaining stage examinations. There are 8 blocks and 40 questions per set. Trust me, with the right practice you can complete each block in the given hour! This gives you an average of 80 seconds per question.

Unlike the USMLE Step 1, this board exam focuses on clinical sciences. Those from newer, smaller, or international schools may not have received significant hands-on clinical training in medical school. This exam alerts residency program directors to a student’s abilities and deficiencies in clinical practice.

What Are the Best Resources for the Step 2?

Selecting the Step 2 CK product with the most high-yield facts can be tricky. You will want to plan the appropriate study time in advance based on the number of questions you wish to cover and how many are in the q-bank.

Here is an overview of some of the key differences students need to know.

Final Recommendations

With the COVID-19 pandemic, Step 1 moving to pass/fail, and several other uprooting changes occurring in medical education, knowing how to assess the Step 2 importance can be daunting!

Luckily, we can see from the most recent NMPR Residency Director Surevey 2020 how the program directors view the importance of this clinical exam. Let’s take a look at the where Step 2 CK stands in comparison to other important factors straight from the horses mouth.

A bar chart displaying the percentage of students interested in interviewing each year for USMLE Step 2.

The first consideration is simply getting your foot in the door. Each residency site has a different process for whittling down hundreds to thousands off applications into a more manageable selection for interviews.

As we can see, your Step 2 CK score has an average ranking of 4/5 as reported by 507 program directors (78%). This average has remained relatively stable over recent years, averaging a 4 out of 5 in 2018 and a 4.1 in 2016.

This is also now on par with the Step 1 score average rating, which was 4.1 in 2018 and 4.2 in 2016. We can expect this shift to continue as Step 1 moves to pass/fail in 2022.

However, being invited to the show is only half the battle! So how does this score stack up to final residency selection?

When it comes to selecting applicants after the interview, interpersonal skills are always key! After all, would you hire someone to work with you for several years you didn’t get along with or had trouble holding a conversation? However, exam scores can still play a role if an applicant is teetering on the edge.

At this stage, Step 2 actually beats out the Step 1 though narrowly. It’s 4.0 ranking has actually slightly decreased from its position of 4.1 in 2016 and 2018. More interestingly is that Step 1 has consistently decreased in importance from 4.1 in 2016 to 4.0 in 2018 and now 3.9 in 2020.

One interpretation of these data is that the board exams are still important but their importance is waning over time. This means that students without the best testing abilities and scores may still be able to lock in competitive residency positions. Of course, you will want to look at the ratings given by your top institutions of choice to see which still covet the USMLE exams and which look for more well-rounded applicants.

In many instances, it’s more important to not fail than to pass with the highest marks. Just remember, you are only competing against yourself. Strive for slow and constant progress and know what, whatever the outcome, you gave it your all!
