Behavioral science, The silent killer.

Pathology, Pathology, Pathology. All of us concentrate on pathology while studying and give it the lion's share of our study time, and we are correct in that case, and some even subtract the majority of the time that should be dedicated to other subjects to be better at pathology. When you ask yourself what subject you are neglecting the answer will be almost always "Behavioral science".
In my home institution, there is no such course as Behavioral science. I didn't study Biostatistics or psychology or ethics during the basic years, while psychiatry is of course studied during clinical years.
So when it came to studying something I'm not familiar with with no assistance or guidance and with the thought that it's not as important as other subjects, most of my friends, colleges and senior students either consciously or subconsciously neglected in favor of more study hours of other more difficult material. Neglecting Behav has proved itself to be a double edged weapon, as you improve other domain you really go downhill in this particular field and instead of getting a push in your score you find yourself losing even up to 20 precious points.
With that said, how can an IMG handle Behav?!! especially for the first time ever.

• Barbara Fadem Books. This beautiful and brilliant professor has written the 3 most relied upon books concerning Behav for the USMLE, 
• The first one which is called behavioral sciences in medicine is the biggest one of them, with almost 500 pages. In my opinion the book is good but not necessarily for the purposes of the exam. You'll find many lower yield information that is not really crucial in your understanding of the information and would rarely be tested and the book could potentially take more time than you intend to dedicate to the subject. I have the book but I didn't use it much and wouldn't advice you to do so.
• The medium sizes one: BRS behavioral sciences. The pearl for the USMLE. The book is concise with a total of 300 pages. I'd advice every IMG who never took Behav or didn't really grasp it to use this book. The book is written in an easy and fast pace, you'd understand what exactly is she trying to tell you plus tables to contrast similar conditions and materials to really get to the essence of the difference between them. The major plus here is the 700 question that is presented both after each chapter and a comprehensive exam at the end. The chapters are small and numerous so you'd get the feeling that you're achieving a lot by finishing more chapters giving you a positive attitude and motivation to achieve more. Overall I'd advice you to use this brilliant resource.
• The small one: HY Behavioral sciences. This book is essentially the modified BRS book. Some details have been removed and the questions were also treated the same. The tables are still there but a little bit modified. If you are already familiar with Behav, then this is the book for you. If you not, I really think you should stick with BRS.

• Kaplan book: a decent book. A lot of student scoring all over the spectrum have used it and they liked it. But for me I liked BRS more. It's a matter of personal preference after all, use the book that you enjoy to be able to absorb the materials faster and retain it better. So, if you like kaplan more than BRS, It's your choice. Stick with kaplan.

• HY Biostatistics: Both Kaplan and BRS have dedicated chapters concerning Biostatistics. Those are brief but sufficient. If you find a persistent defect while solving then I'd advice to get the HY book and study it. It's highly rated by most students.

• Ethics: Fisher's book of course. The book is simple but clear. Many of what seems complicated situations in the eyes of international students are presented easily and the explanation is clear. Do this. Do NOT do that. Period. The book has like 107 cases and detailed explanations at the end. Those are of an excellent quality. Overall this book shouldn't take you more than 1 day is you are doing it more towards the end of your prep.
• Kaplan Videos made by Dr. Steven Daugherty. I like him, and if I like a professor I really concentrate with every word he says or speaks. You can follow with his lectures along Kaplan, BRS or even First Aid directly. What seems as complicated and non-related materials when read alone starts to make sense when you listen to them from someone who understands what he is talking about. With that said I can only give him A+ rating.
