I would compare my case to worst scenario possible, so I hope my experience will at least boost those who have lost hope but still have no option but to go for it.
1) I had 3 weeks in b/w my CK and CS dates
2) I had no knowledge what CS is all about, all I new was my CS date was on 24th Jan and I have one sealed Amazon box containing
firstaid in my closet.
3) I had no study partner.
4) I had to plan my trip to Chicago, book hotel and all stuff in this time frame.
5) and take care of myself and my coming baby
So immediately when I was done with my CK, I tried to reach every possible person i could thrugh phone, email, fb, orkut and so on to get to know what I am going to face, but believe me NOBODY responded (this is no exaggeration). The only help I got was from this forum..thanx
so my first step was to get familiar with exam process for wich I read first few pages of FIRSTAID and saw video of orientation material on website.
After getting lil oriented I did my first reading of FIRSTAID and during that I practiced writing Patient Notes as much as i could in timed manner.
Then did second reading ,this time in a way like reading one case e.g. of abdominal pain completely (history ,exam,DD,lab and everything from last 2 units of firstaid)
And then did 3rd reading,this time made notes(not that elaborate )just 1 page protocol,what not to miss in history and exam of particular case. i mean focused, as everybody remembers general protocol but what is important is certain specific thing that help to rule out or in diagnosis.
Then I was left with few days in which I subscribed for UWORLD, and did go thru that+ did practice some cases on my own. as i had no study partner.
Then my exam was in Chicago, believe me among 25 students I was the only FMG, and only student who wrote PN, all were typing and so tension free that made my situation worst

. but I didn't lose hope
I had 12 patient encounters , believe me in 3 cases I couldn't even come to know wats going on wth them..no clue of Dx. but i followed complete protocol given in firstaid without freaking out and jus wrote my approximate Dx.
Wat helped me most in managing time was doorway info, believe me giving some time at door helps a lot inside room. in every case I wrote name of pt. any abnormal vitals if any otherwise didn't bother to note them (WNL) and wrote CC. with CC I quickly noted down DD, so that inside I was focused what to ask and what things to rule out, this really helped in getting flow and being focused + off coarse u need to ask PAM HUGGS FOSS.
I will not say I did perfect but i messed in certain cases horribly , but what i tried was to follow the protocol and keep urself calm and cool and think about 1 case at a time
Now since i passed i could share this but believe me when there is hard time never loose hope ,give your 100% ,never be overconfident, its not only ur proficiency and communication, it is amalgamation of all , as we have to pass all 3 not jus 1 section
I wish others best of luck.....
