There is no way around it. This is the book you MUST own and cherish. Upper year students called it ‘The BIBLE of Medicine’. Start following through your classes with this book (casually but starting on your day 1 of your medical education). Majority of the study aids out there (e.g. Osmosis) reference back to this book. Editions change each year but probably nothing much will change until your first step exam(depending on how early you write the test though).
