The essential companion for your first two years of medical school From Tao Le, author of First Aid for the USMLE Step 1 First Aid for the Basic Sciences: Organ Systems, 2e provides you with a solid understanding of the basic sciences relative to human organ systems with which all medical students must be familiar. The second edition has been completely revised to feature a more student-friendly and approachable text, an updated high-yield rapid review section, new images, and more.
Like I said in my review for the Basic Sciences one, quite good, but still don't depend only on this guy. The regular First Aid is significantly more concise. Pharm in here is also all over the place, so I would say look at that from other sources. Very good for Physiology and Path, though.
