I picked it up at a used book sale. If you're happy with a Step 1 score somewhere between Pass and 215, this is probably enough for your pharm review. If you're hoping for above average scores, you'll be better off with Middle Sized Katzung.
I'm not exactly sure what my Step 1 pharm strategy is going to be-I have a sinking feeling that Pharm is going to stand out as one of my weak areas, meaning that I'll probably spend more time with Middle Katzung than Baby. I'm going to start my first day of Board studying with the full length 350 question Kaplan diagnostic, and let it tell me what I need to focus on!
