I have the 3rd Ed also. I think they are great study tools for lecture and *hopefully* boards. I find they are more useful if you use them with someone. Even a non medical person can read them to you... or find something to cover up the answers at the bottom because because they are written so big you see what it is before you even flip the page. I've used mainly the pathophys ones.
You can find the 3rd ed really cheap too 🙂
