Don't feel compelled to seek out these retired exams; most students including those who do excel on Step 1 don't use these old exams. The format of these practice exams differs from the actual Step 1 exam in two key ways.
NBME practice exams are comprised of 4 sections composed of 50 questions each. With 1 minute and 30 seconds theoretically allotted to each question, you have 1 hour and 15 minutes to complete each section and 5 hours total for the whole exam.
The actual Step 1 exam is comprised of 7 sections of 40 question blocks, corresponding to 1 hour per section 7 hours total. Surprisingly, the UWorld question banks and practice exams best recapitulate the actual testing interface. Taking the Self-Assessment. The exact timing of the first practice exam can be a contentious issue. Some argue that it should be taken at the very beginning, right before your dedicated study time. On the one hand, doing very poorly or even failing such an early exam can provide for a very motivated beginning to your studying.
Additionally, it could give you a sense of which areas you are weak on. Personally, I did not take an exam at the very beginning of my dedicated study period, ascribing to the latter rationale. Instead I took the first practice exam right after my first pass of First Aid. Regardless, an exam first or second should definitely be taken several usually at least six weeks before your test day.
Establishing a baseline score is crucial. It will lead to a drastic shift in your study approach if you score below a on your first practice test in particular, this can suggest that you will need a more intense dedicated study period to catch up. For the remaining exams, allow for at least one to two days between them to adequately review the answers.
It should be noted that some test takers combine one NBME practice exam 5 hours with 2 of the 4 sections of a UWORLD self-assessment 2 hours to approximate the length of the actual exam. Here is the histogram provided from the NBME:. Take a moment to compare it to the Step 1 histogram above. Specifically, Step 2 CK scores seem to skew even more positive from the predicted scores. And probably by a lot.
Those statistics are pretty remarkable, particularly for Step 2 CK. By comparison, many fewer Step 1 students will accomplish this feat. This squares with my experience. Why is there such a difference in the predictive power of the Step 1 vs.
This may hurt their predictive power. I suspect, however, that the difference in predictive power is due to the exams themselves. Much of Step 1 involves mastery of content. Doing well on Step 2 CK, however, involves much more question interpretation. Knowing what each sentence means in context — in a timed setting — is a huge challenge. This likely causes both the NBMEs and the final scores to be much more volatile. There is no official explanation given for why, although we can speculate.
This has been my experience. Why such large swings? As we discussed above, QI ability fluctuates day-to-day much more than content knowledge. Thus, you would expect performance on Shelf exams to be much more volatile. The bigger issue, however, is likely due to sample size. The Shelf-specific assessments have only 50 questions. Each Shelf exam is questions, whereas Step 1, which has the fewest questions, has items.
Like with all small sample sizes, there will be much more variability. There is no score given for the lone NBME. It is rare to score far below your predicted score see above. First, remember you should never take an NBME more than once. Repeating the same NBME reduces their predictive power. Recalling questions, even vaguely, can change how you take the test, and can inflate your score. Second, boot-legged copies of NBMEs are unlikely to give accurate scores.
Every NBME has a different scale for how much each question is worth. Third, statistically, a small number will experience large swings in scores.
This is true for normal distributions, although as we saw above, this is rare. They changed their entire approach i. Their scores plummeted below their predicted up to a 70 point drop in one case. Over the years, the NBME has given more and more information out for each exam. Previously, they only told students which questions they had gotten wrong.
Subsequently, they gave students the correct answer. But only for the items they got wrong. However, you will NOT see any explanation of why other responses were incorrect. They announced that we should expect explanations for other NBMEs later in It depends. On the one hand, as a way of learning, reviewing an NBME is frustrating.
After all, there was a reason you got the question wrong in the first place. You may find answers on message boards. However, the quality of those explanations may be suspect. Be sure to assess how many questions you missed on topics where your knowledge is already good. In other words, they:.
How do you interpret a shelf exam score? The NBME shelf exams were originally scaled to a mean of 70 and a standard deviation of 8. Keep in mind, this is not recalculated every year.
The actual average in a given year has tended to creep up and is usually somewhere in the low-to-mid 70s. All this arbitrariness can feel unfair and frustrating to medical students, which is what makes shelf exams so important. As a standardized multiple choice test examining everyone on the same material, the shelf exam is the only truly objective tool for evaluating students on their clinical clerkships.
The standard test has four minute sections, each with 50 questions. Highest score I've ever seen was While the USMLE program does not disclose how the three-digit score is calculated, Step 1 scores theoretically range from 1 to , most examinees score in the range of to , the passing score is and the national mean and standard deviation are approximately and 20, respectively. The NBME has correlated each form with students' final scores.
Five sections; 36 items each. Between 3 hours and 20 minutes to 4 hours and 24 minutes. Self - Assessments are delivered over the Web. You must log in to access a self - assessment and complete it within 90 days. Uworld doesn't make any sense at all until you've synthesized and essentially learned all the info. Wait until you're 1 month out from dedicated and then start with Q's a day.
You'll finish it twice easy. Approximately seven hours in the test session on the first day, including 45 minutes of break time and a five-minute optional tutorial.
