So, I will be a 2nd year at a new medical school (LMU-DCOM) and we have no upperclassmen to ask book-related Qs. We are starting Heme/Onc and Cardio as our 1st 2 systems in the Fall. For Heme/Onc, the "required" book is Essential Haemotology. For Cardio, we have Dubin and Clinical Electrocardiography, A Simplified Approach (7th Ed) by A. L. Goldberger both for EKG; Physiology of the Heart (4th Ed) by A. Katz We also have Felson's Principles of Chest Roentgenology by L. R. Goodman as a required text. My question, to any of you upperclassmen at any school, how useful were the above texts towards learning the material? Is it necessary to purchase or can using class notes and board review books good enough? Thanks for any and all advice!
