I got my result today and I passed. The materials I used were kaplan notes with videos, all sections of MTB 2 and the non-IM sections of MTB 3. I also used kalplan qbank and UW.
I first started off with kaplan notes and videos. After each section I would do the corresponding questions in kaplan qbank. I would annotate notes into MTB 2 and 3 from kaplan qbank. After I completed kaplan qbank, I read both MTBs from cover to cover. Then I took NBME 2. I then started UW and started reading both MTBs simultaneously. After finishing MTB cover to cover again, I took NBME 4. After that I stopped reading and focused on completing UW. After finishing UW I again read MTB cover to cover. I then read the IM section from MTB 2 before my exam date. I bought UWSA but didn't have time to do it since I gave more emphasis on reading.
Kaplan qbank: 63%.
UW: 73%. Timed, tutor.
NBME 2 3/26/13: 232
NBME 4 4/17/13: 239
UWSA: didn't have time
Step 2 on 5/22/13: 248
I had 8 blocks with questions ranging from 43-45 Qs. I would mark between 10-15 questions per block. If I wasn't 80-100% sure, I would mark. The questions were not as lengthy as people were saying. To me, they seemed similar to UW question lengths. I finished one run through each block with about 15 mins left then I would go back and visit my marked questions.
Unfortunately, I found this exam harder than UW. I wasn't expecting this and I didn't feel good coming out of the exam. I also felt awful during NBME 4 (more during the real exam because it actually counted) and thought I was gonna fail and not do as well as nbme 2. There were about 5 questions per block that I could only narrow down to 2 or 3 choices, so you have to go with your gut. However, the materials I used gave me the knowledge and you have to be able to apply it during the exam. You may feel awful coming out the exam (I felt great coming out of step 1, but scored about 10 points less than this ck exam), but have confidence in your prep since it won't lie. That's all I can think of. Ask away.
