In my opinion, the most valuable kaplan book is kaplan's biochem book. Path, again in my opinion, is definitely not the best path source out there. I have read both goljan and brs as well as the kaplan book and would pick either goljan or brs over kaplan any day....goljan has pictures, too, which is nice, and you can use it w/ the audio (ie read a chapter, listen to corresponding audio, etc). Micro, what I read anyway, was too much info and not that well presented...I think you do really need to know the bare bones/clinical presentations/how to differentiate bugs, and that gets a little lost in the text of the micro one w/ a lot of extra random facts that can be distracting from the main point. The flow charts and charts comparing presentations at the end aren't bad, but again, I think other sources (ie made ridiculously simple and first aid) get the take-home message across a lot more clearly and consisely. For immuno, I looked at high yield and kaplan, and wasn't crazy about either, but either one probably does the job of what you have to know. Goljan path incorporates some of this as well. I only read part of the phys book b/c it was sooo long, and thought it was so-so. Again, I think brs phys does a better job at driving home the important points, but I would guess Kaplan also covers it, just with many more words....I didn't read kaplan behavioral/biostats at all, just b/c most of the other books were pretty disappointing and I was runnning out of time to compare sources. I was pleased w/ high yield and brs (this probably would be overkill for most, but my school doesn't really teach either of these subjects). Lastly, I thought the anatomy one wasn't particularly helpful, particularly gross. Neuro was OK, but I was clueless on neuro beforehand so anything would have been better than what I knew. I followed it up w/ high yield neuro and got some more info out of that book. Finally, pharm...I didn't like the pharm book since it had a lot of words but really not all that much useful information about mechanism/phys....I ended up using it to get the drugs not in first aid, but don't think it helped that much. Probably wouldn't read it again if I had to do it over, but I do think that after taking the pharm shelf/final at the end of the year, I knew pharm pretty well going in.
In summary, I see you've posted a lot of q's about the utility of kaplan. I think that their stuff isn't terrible, with the exception of path, but I think there are other sources out there at least as good and in most cases better/more consise and definitely cheaper than kaplan. If I could do it again, I definitely would not have bought kaplan, since the only book I think I really benefited from was the biochem, and I even heard that the rapid review biochem book is better than kaplan from a classmate. I think goljan lectures are really good, so I would listen to them in addition to (or instead of) kaplan, but I don't think you should skip goljan for kaplan. UNless your videos are of goljan teaching for kaplan or something.
But, I haven't gotten my scores back yet, so this is just my opinion based on what I've done these past 6 weeks or so, so take it w/ a grain of salt. Best of luck!
