UWorld Step 2 CK Questions Over Time

UWorld Step 1 + Step 2 CK Questions Up Dramatically Since 2018

Looking at the data graphically, it’s evident that from 2018, UWorld has dramatically increased its number of questions.

Amboss Launched in the Spring 2017 in the US

It’s hard to ignore that UWorld drastically expanded its QBank questions roughly a year after Amboss entered the US scene. Coincidence? Possibly. A more compelling explanation would be that UWorld felt the need to expand to head off a competitor.

Concluding Thoughts

UWorld has dramatically increased its Step 1 and Step 2 CK questions since 2018. We can speculate as to why, but the truth is that there are many more questions now, with that number likely to continue to increase.

What does this mean if you’re preparing for the USMLEs? First, it is much harder to finish UWorld – let alone do multiple passes – now than it was in the past. Second, you should still remember to focus on learning the material well rather than rushing through a QBank just to say that you did it.
