I'm not sure if you posed the question again to revive the topic or if I wasn't clear - I probably wasn't clear b/c I tend to ramble ...
Yes, I found HY BnB + First Aid Behav Sci + First Aid Neuro to be plenty-good for the exam (my score's posted elsewhere on sdn). If you get HY BehavSci, do not bother getting HY BnB, and vice versa, because all of BehaviSci is shoved in BnB. The glory of HY BnB is that if you buy that one book, you do not need a separate neuro book ... in summary:
HY BnB ... OR
HY BehavSci + HY Neuro ... OR
HY BehavSci + USMLE Roadmap Neuroscience (this neuro book doesn't get much attention, but I would have definitely chosen it over HY Neuro had I not already purchased HY BnB)
