UWSA2 or NBME 13

This forum made possible through the generous support of SDN members, donors, and sponsors. Thank you.
I did 7, 11, 12, and 13 along with both UWs; if i had to pick one it would definitely be NBME 13. UWSA 2 had a pretty ridiculously generous curve and i felt the questions were much different than UW 1 and the NBME exams. On the other hand, i felt NBME 13 was a good test. I have not taken Step 1 yet, but it seems the later NBMEs are most representative of the real exam.
 
I'd say do both if you had time but if you're close to your date just do another NMBE. The Assessments overestimate most peoples scores anyway. At least with the NMBE, you get a more realistic number along with practicing with real questions to get you in the right mindset for the test.
