tudied for about a month

Uworld first pass (58%)- done throughout 3rd year
Uworld second pass (69%)- during last month
NBME6 (2 weeks ago) -440 (226)
UWSA (today) -450 (206)

wtf? Am I getting dumber? and how is a 450 206?

Help!

Dear friend, as you assumed there is difference between these 2.
Yes, unfortunately, CK NBME is not as accurate as step 1.
Therefore, go ahead based on UW SA. I have seen bunch
Of my friends who trapped in the NBME score. For example,
a friend of mine who had 269 on NBME got 247 on real test.
Don't get confused by that. Have a great time.

Good luck with your studies
