The effectiveness of any study course is obviously partially dependent on the individual and what works for them. For me, the ACCP materials (chapters, audio and video files) were adequate. I was able to source electronic copies on this forum. I then printed out the chapters (yes that meant a lot of printing!)
Considering I am a foreign pharmacist having never practiced in the US and passed (low to mid 500s score) on my first attempt, suggests to me the ACCP materials should be more than adequate for most. How did I study?
I listened to the lectures while driving to work each day which for me is a 25 minute drive each way. I also read all of the chapters and watched most of the videos of the presentations. I started three months before the exam. I listened to the lectures multiple times over. I did all of the questions in the chapters. I had access to other materials including mock exams and some high yield stuff but never got round to looking at it.
My advice is know your stats and regulatory stuff well. Some (I stress some) of the clinical stuff you should be able to answer in your sleep, and you'll need to study up in less familiar areas..... but looking at the breakdown of the exam, if you studied nothing else but the stats and regulatory stuff and nailed those elements, you are close to 50% home with the exam ..... one would hope as competent practicing pharmacists, you could use your base knowledge to get you over the line by getting some clinical marks!
I studied everything and would study the same way again. Listening to lectures and reading works for me, but whatever your method, start studying early and give yourself enough time to cover everything. Did I remember everything I studied? No! I repeated the lectures a number of times and read all the chapters at least once, some twice, and some of it obviously stuck!
Hope that helps someone.....
