My take---

Doable, but more about endurance. By the last block i was almost delirious. I studied about 3wks., 6-8hrs. daily. I read secrets, and crush step 3 (yes, step 3 because i like the organization better. It helped me remember more). I did purchase board/ward, but my opinion is was a little over kill, esp. after taking the real thing. The thing that helped the most was UW. If i had to do it again, I would stick with UW and Secrets only. If you take months to study you should do just fine. If you have a average foundation, I think you'll be fine (...know everything 80%).

Experience--
I had 3 audio clips (listening only), you could arrive at answer by reading case. I had 3-5 ECGs. The exam was pretty well spread out as far as topics. I did have a hand full of questions that dealt with basic science stuff.
One day before, I would recommend watching a movie and getting a good night sleep.

My 3 most valuable pieces of advice is: UW, UW, UW

i will post more details later, if you have specific questions I will be more than happy to answer. I am exhausted!
