If you're weak in neuro I'd recommend going through kaplan (would take a couple dedicated days, maybe less if you're motivated). It's systematic and will give you the foundation to approach everything else. FA neuro is just like FA for everything else--a study guide at best, and out of context it's hard to digest. But if you're already solid on the neuro basics then no need to use kaplan IMO. I didn't like HY neuro; I'm not sure why everyone recommends it, but it's got a lot of info that I have yet to see come up on any of my 1200 UW questions. BRS physio neuro has some info that kaplan doesn't. definitely worth reading as well, but I still recommend kaplan overall
Edit: oh yeah I remember why everyone likes HY neuro: all the brain scans with labels. I'd agree it's worth putting down $5-10 for a used copy to see those pages.
