If there is something that I learnt in my CS experience, that's the word.
I gave my exam in first week of May, and I think its a pretty do-able exam. I did FA once on my own and then with a SP via skype. I also had some live SPs towards the end of my preparation. I would definitely recommend Live SPs. you get that real time experience, but even if you don't thats okay. I used to practice with 14/9 mins, later did 13/8-81/2 mins for Pt encounter/pt note. It helps! Big time! Probably read/practiced for around 6 weeks, and thats way too much now that i look back at it. i guess 3-4 weeks is more than enough.
About the exam, yes time flies by! You won't have time to think what went wrong in the previous case, so don't. I used to write at least 3 probable diagnoses and few mnemonics LIQRAA/DOPEFAAA etc, it helped me a lot! if i got stuck, i just used to take a look at those and would get reminded of some q to ask. PE was very focused. Counselling is THE most important part. if running short on time, cut down PE and go to counselling. Give the pt a chance to ask a challenging q, ask if you addressed all his/her concerns several times. And be Diplomatic and Empathetic, like I can understand your apprehension/concern and that it could be one of the possibilities, but right now I am not sure, need to run some tests blah blah, FA has some good examples.
In short, I guess my exam was OKAY, i did a few mistakes here and there, my diagnoses were jumbled up some times. But I hope I pass, have to wait for a looong time before the results are out.
