USMLE Step 2 CK "free 150" Questions - 2013 +USMLERx

Like for Step 1, Step 2 CK has a handbook, which you should be aware about, and it contains a 3 block - 131 question exam at the end with answers. Some people call this the "Free 150", i think, unless there is another exam I am unaware about. But this exam is OFFICIALLY released by the USMLE on their website and you shouldn't neglect it.

Here you go!
And great luck!
