These postcards are awesome! You have 8 different sections, each with important information. For example, the cardio section offers EKG reviews, how to read EKG rhythms, heart sounds and murmurs, lab values, and more! Very good quality cards! And I really like how they send an extra reel with a badge to put on the cards. So if you study neuroscience or pharmacology, you can just grab this section and take it to work or something. I am very happy with my purchase!
