I took it a few weeks ago. They love heart sounds for some reason as well. My exam had a fair share of OB and Peds, but nothing out of ordinary. As far as IM they focused on Neurology, specifically concussion protocols and bleeds. OMM was not bad, but there is some stuff for which you can't prepare for.
As far as the last section, my computer froze because I was scrolling up and down using the cursor on the right side of the screen. It was frozen for 2-3 mins and they had to restarted the computer. Luckily, I began the section like 10 minutes earlier so I didn't panic. In all I probably lost a 2 minutes on exam time. I would go over the previous CDM questions on NBOME site. I had two peds cases on my CDM section for a total of 8 cases. Once you press next you can't go back.
Like apple3, I didn't feel great but all you need is a 350 to pass and the prospect of never having to do OMM again made me smile. Good luck to rest of you guys!
