WHEN TO START PREPARATION FOR THE USMLE STEP 1
Use First Aid book as early as possible while learning the basic medical sciences. The first semester of your first year is not too early! Devise a study plan by reading Sections like guide to efficient exam preparation from first aid book and make an early decision on resources to use. Note that First Aid is neither a textbook nor a comprehensive review book, and it is not a panacea for inadequate preparation.
