hi raj, i used the md pharmacy law book, not the huge red one, there is one baige/light brown colored one (cant remember the exact name) but i called the board of pharmacy and ordered it from them. Just specify if not they may think you want the red one. Also i used a lot of practice questions (ill check my email if i still have them) and focused a lot on the DEA laws and controlled substances. Make sure you know those inside out!
