I have these but didn't end up using them. I find that the drugs I learn for classes don't follow the Lange charts very closely (we learn some that aren't listed, and some are listed that we don't learn. And some that are listed - we learn at some poin in the future), so it ends up being confusing.
I end up making my own drug charts for class, and I'm planning on keeping those for the boards. Sometimes when I learn things in a certain order or in a certain grouping, I have to see them in that same format again for it to jog my memory.
I've heard that pharm cards are good for the boards, and I've also heard that the drugs in FA are sufficient.
